Hey everyone!
Long story short, I just recieved a rust-free 1974 Pinto Squire wagon with only 42K on it in exchange for a batch of my homemade sugar cookies.
The original owner (my grandpa) didn't like over-the-shoulder seatbelts and removed the bolts on each seatbelt that attached them to the ceiling of the car. Does anyone know or would anyone be kind enough to check yours and see approx. what size bolts I need to get to fix this? Would there be any easy way other than grabbing 1,000 different bolts and spending all day trying to find the right one?
Thanks for any help,

I fould the belts I took out of my car, but could not find the bolts to go with them. The stock bolts are torx heads, but a regular bolt should also hold it. my guess would be something near a 3/8 NF bolt.
The bolt is a 7/16 NF T50 torx head. There is a threaded coupler welded to the inside of the B pillar. It has 9/16" of thread. I would buy a bolt with 3/4"of thread and a washer. The metal part of the seatbelt that you are bolting back up will fit over the outside of the coupler.
The hole in the seatbelt is .680". The head of a stock torx bolt is .840. This only gives you .08 of clamping. I don't know if there was a washer on there from the factory, but I have one on mine.
A stock 7/16 bolt is .625- .603 across the flats and .722- .687 across the corners (Machinery's Handbook, 19th Edition).That's little or no clamping. I would use a washer if you are going to use a regular bolt. Be careful if you get a bolt that is longer than 3/4". There's about 1" from the face of the coupler to the inside of the B pillar. If you get a longer bolt, it will dent the outside.
A 7/16 x1"x3/4" socket head (allen) shoulder bolt, should be a pretty colse match for the original bolt, & it'll be grade 9 hardware to boot. the original Torx was a hard bolt (dunno the grade) with a washer (probably a 3/4 flat washer would due) there is also a 7/16 lock washer under the Torx bolt. Hope this helps I took measurements from my '74's anchor bolts.
Something to rember while shopping for those type of bolts is that they are a verry fine thread. I dont know the thread count but its not something that is usualy offered at Home Depot.
I don't have a 7/16 NF bolt handy to run through the threads in the car, but I did run the torx that came out through a die. It's a 7/16 -20. You should be able to find that at a hardware store under fine thread bolts.

What size are you refering to?
A standard 7/16 Hex Socket Head Cap Screw Will have a Head Diameter of .656-.642".
Most will be grade 8 or 9, but watch out for really cheap ones.
Thanks a lot for the input, everyone! I'll go bolt hunting tomorrow with all of that info and hopefully find the right fit a lot quicker than I would have without your help.

I mentioned a shoulder bolt, that would have a 7/16-20 thread and a 3/4"shaft up from the threaded portion. up from the shaft there would be a 1" head requiring maybe a 5/16 or 3/8 allen wrench to turn.

If you can't find any, let me know. I have some on a '76 wagon that I am parting out.
