I'm picking up a 76 runabout in a couple days and have plans to do a late model turbo swap with a 5speed. I want to run the 8" and this was very good info. Thanks for sharing. I just hope the car already has the 8" in it!

Some more info for those looking for a 5 lug 8":

The 65/66 mustangs with a v8 had the 8" rear, but it is narrower from drum face to drum face than the later 67/68 stangs (two or three inches, I do not have the exact dimentions, but they are much closer to a pinto rear). The rear in my car is about 59". The 65/66 ones are easy to pick out of a crowd, as the housing tubes taper near the ends (like the 23 spline pinto 6.75", pre-79), but all of them 65-68 have the same perch widths and size. The tubes on the 65/66 have the same diameter as the pinto ones. These are not a bolt-in for a pinto, but they are not too hard to install. I have one (full assy) from a 68 in my pinto. The outisde to outside edges of the perches are about the same as for the pinto. I slotted the perches (off-center to the perch itself) to match the perches (on center) for the pinto. I then welded a 4inch piece of .5 rod to both inside edges of the perches to give it more support. I also had to open the holes on the mount brackets and use the u-bolts (1" longer than stock, I got them from Mustangs Unlimited) from the 68. I have stock 14" x 6 ford steel wheels with a 4" backspacing on the rear now, and have no issues with rubbing. I will admit it looks strange from the rear, but the rear sway bar gets you attention off of it.

I want to get a pair of 14" x 7 (5.5" B/S. custom made) race rims that will help the "look". I then want to cut the bead area off of a set of stock 13 inchers, and weld the hoop to the 14 inch wheels. Then a set of stock hub-caps will pop right on for the sleeper look.

I will get some pics as soon as I can.

You can use the Rear disc brakes from an Explorer. They work great.

Do you have any information on how much work is involved in doing this swap? I could really use some fast info on this as this would help me in the next 2 weeks before racing season starts. Please email me at HolcombRacing@yahoo.com . ThANKS

Maverick 5 lug 8" rear axle info:

1) The 5 lug ones are 5 on 4.5" and were on ALL 1973 and later Mavericks. The earlier ones had a 4 lug as well, but it is not the same lug pattern as a Pinto (4 on 4.5").

2) They are about .5" narrower overall than the Pinto 8" rear (ABOUT 56.5" drum to drum). IF the shafts are installed in a Pinto housing, they will engage the splines .25" less for each side; This is something to think about BEFORE doing. I have a pair of .25 wheel spacers to put it at the stock pinto track width.

3) The perches are not set-up to use the rubber/block assy.s.

4) Like the 67/68 Mustang ones (and others), the perches are narrower, and have a different O/C measurement, but the outside edge of the them are about the same distance apart as the Pinto perches (about 45").

5) The bearing retainer plates on the Mav. are the same as the ones on the 67/68 Mustang, but NOT the same as the 8" Pinto ones. My plan was to put the shafts in a Pinto rear, but I would have to pull the bearings off the shafts to switch the retainer plates, and along with the spline isssue, I just re-worked the perches like I did on the 67/68 rear to install it.

6) The tubes do not taper, they are 2.75" to the brake plate. You will have to use the Mav. shock plates and bolts (if you do this I think it will make the install very easy, but you will lift the rear of the car), or slot the holes in the Pinto blocks and plates; I slotted mine to run the M-II rear sway bar mount shock plates.

7) They take the same axle seals (two parts places told me otherwise, but they were the same as the 68-73 Mustang and the Pinto 8" rears).

They need drums and wheels with the BIG center hole. The drums from my 68 stang rear would not fit (good thing the Mav. ones were in good shape, as a matter of fact they had more meat on them). They need rims with the 2.75" center hole, the same size as what is needed to go on a Granada rotor.

9) I will post more if I find any more details.

10) Link to photo of what I did to modify the Maverick perches: http://www.fordpinto.com/smf/index.php/topic,953.msg31360.html#msg31360

11) Hope this helps.

Maverick 8" rear axle info (later years at least):

1) They are 5 lug, 4.5".

2) They are about .5" narrower overall than the Pinto 8" rear (drum to drum).

3) The perches are not set-up to use the rubber/block assy.s.

4) Like the 67/68 Mustang ones, the perches are narrower and the outside edge of the them are about the same distance apart as the Pinto perches (45"), on-center they are different.

6) The tubes do not taper, they are 3". You will have to use the Mav. shock plates and bolts, or slot the holes in the Pinto blocks and plates (like I did).

7) They take different axle seals.

Hope this helps.

What are the dimensions of the holes and how critical is the precision? Are they something that I can torch out or do I need to measure twice and then carefully drill and dremell?

It is critical that the holes are the correct size and location so that the rear is installed where it needs to be, otherwize the rear will be too far forward, to the rear, or sideways. Some aftermarket springs have the pin in the wrong location anyway, so you can use this as a way to re-center your axle.

Not something I would do with a torch.

As for the size, they are the same as what is on your Pinto axle. I don't remember the size drill I used.

I used a hole saw, drilled two holes with it and used a cut-off to join the two, and some work with a file....

You can just drill one small hole and use the Mav. shock plate if you wanted.

I guess that I have to resign myself to a bit of measuring and cutting when I get both axles dropped.

Vaguely annoyed that the wagon that I got is one of the rare ones without the 8" rear and had the wimpy 6.75" one instead.

I got my Maverick axle home and discovered that the bolt circle is about 1/4" bigger than my Pinto bolt circle. What's up with that? What now?

Pintony · « **Reply #45 on:** November 07, 2006, 05:59:45 PM »

Well Doug...
I thought there was a part in this conversation that said that the mav rear was 4 on 4.5 but I could not find it.
The only rears that have the factory 4 on 4.25 bolt circle are the M2 and Pinto V6..
If you are really slick and steady handed AND you are using old school MAG wheels you could elongate the bolt holes on the wheels or try some different axel combos.

that maverikc rear end is the one I been looking for...offered on early 71-73 Mav's and Comets with a 200 and automatic. the 8 inch rear is a 4.5 x 4 lug like the Falcons,Mustangs and Comets of the 60's. the Mustang II/Pinto axles dont fit the rear ends at all.

Not many Mav's in Oklahoma salvage yards....

So want to trade axles?

FCANON · « **Reply #48 on:** November 08, 2006, 08:24:32 AM »

Sorry but the axles dont swap...they have a odd tappered small bearring.
If I had a MustangII or Pinto 8 inch to spare I would swap you.

Frank

dholvrsn · « **Reply #49 on:** November 08, 2006, 06:42:00 PM »

Is there a Maverick group similar to this group where I can ask about an axle trade?

Am seriously toying with the idea of drilling a new bolt circle in the Maverick flanges.

Did redrill some Studebaker Hawk hubs to take '50s Cadillac sabre wheels and that was a true pain.

77turbopinto · « **Reply #50 on:** November 08, 2006, 08:47:54 PM »

I was tempted to put the Maverick axles in the Pinto 8" housing (mine had the same bearings). It looks like it would "work", BUT, the axles are 1/4" shorter (each), so 20%-ish less contact in the splines. Also, the retainer plates would need to changed, so new bearings are in order for that. It was easy just to modify the perches and install spacers behind the wheels.

A machine shop might be able to drill those for you too, I just don't know how much room the flanges have for the new hole pattern.

I got the studs redrilled for the smaller bolt circle now. I am waiting on the parts store to get the seals in. Now where is a good place to get new U-bolts to clamp the axle down?

BTW, IIRC, 6-3/4 backing plates don't fit on 8" axles do they? Although I may swap the finned drums across.

douglasskemp · « **Reply #53 on:** December 14, 2006, 09:19:32 PM »

Any good auto parts store or 4x4 shop should be able to get you u-bolts. Just get the three dimensions you need: length, diameter of the axle, and diameter of the bolt.

dholvrsn · « **Reply #54 on:** December 28, 2006, 06:15:41 PM »

I got the new U-bolts. The axle swap will start on my next days off. Now many foot-pounds do I torque them down too?

dholvrsn · « **Reply #55 on:** January 09, 2007, 08:02:20 PM »

I have the axles sitting on the springs and snugged down. Boy, it was a pain to get every thing back together and aligned! Now I'm ready to tighten it down and would love to know the torque specs for the U-bolts and the shackles, please! Thanks!

Hi all, has anyone had success buying aftermarket 5 lug axles for the Pinto/MII 8"? I called Currie, their rep said "No way their axles would work", even if I used the original (smaller) retaining plates.

Any ideas short of having the standard small bearing ends welded onto the housing? Has anyone else run into this?

WagonNut · « **Reply #57 on:** April 15, 2007, 09:29:06 AM »

Hey turbopinto72,

Thanks for the great info on these axles. I like many others am looking to convert to a 5 lug rear. I want to retain my Pinto rear and chang out the axle shafts. I know how to do this with Granada axles as it has been well documented. I have given up searching for Granada axles and have found a set of 66 Mustang axles. I read your post about the differences in the Pinto axle shafts from the 66 Mustang.

The bearings are the same but the retainers are different. I should be able to correct this by pressing off the bearings and using the Pinto retainers on the 66 axles.

The axle length of the 66 is about 1/4 inch too long. I would like to cut the 1/4 inch or so off the ends of the 66 axles and re-chanfer them.

The 66 axles are thicker in the middle. Will this prevent me from swapping them?

I would use the stock backing plates and brakes, but would look for 9" 5-lug drums. I have the axles coming and am willing to experiment to make this work. I know it would be easier just to re-drill the axle shafts and drums to 5 lug, but I'm not comfortable with doing that.

Any thoughts that you (or others) have on this would be appreciated.

Thanks in advance, Kevin.

I have a MII 8" 4 lug rear and want to go to 5 lug axles. Since this will be a turbo 2300 I am planning to put in aftermarket axles.

Now the questions to make sure I understand correctly.

Do I need to change the bearing retainer plate?
What is the best brake drum to use?
The internal componets to the brakes are the same, yes?
Can I use the same backing plates.

Obviously this is not a high dollar car so i have to watch my pennies but I want to make sure the brakes are right and safe.

Thanks for any help for this newbie at this 8" rear stuff.
