I am in the process of installing factory air into a 74 runabout with 2.3. Would anyone have some pictures of the brackets and belt alignment on the front of the engine. I pulled all this stuff several years ago. The issue I am having is getting all the pulleys to align correctly. Car also has the thermactor system which originally the pump mounted low on the right side. Now it looks like it mounts above the A/C compressor. There must be some different pulleys that were used with factory A/C. It looks like the crank pulley must have been different would appear that A/C drives off front grove which is where thermactor originally drove and it was a narrow belt. Not sure now where thermactor would drive as it appears to align with the alt grove. So hoping maybe someone has a few pictures to might clear this up. Unfortunately the engine has been pulled out of the car I got all these parts out of so I can not go back and check that way any longer. Thanks for any help. Dennis

Thank you for the pictures. After more research I determined that the crank pulley and the pulley on the A/C compressor both needed to be changed. I would assume the donor car that I pulled the A/C from was a 49 state car. That would explain the single grove pulley on the A/C compressor. I just did not realize at the time the crank pulley was different. Found a NOS crank pulley at a dealership in Texas (White Motor Co). Last one according to the parts locator my local dealer used. They were quite happy to part with it and at a very reasonable price. The A/C pulley was sourced through Greens. So should have the parts sometime at the beginning of the new year.

I have a 76 with factory air.
If you still need detailed images, just let me know.

Best of luck with on going work.

The actual install was not that bad. Of course with the windshield out it made it very easy to pull the dash and then have room to work on things. I put a new core in it before it went into the car. While I was replacing the core I also replace the door seals and did a general clean up of the inside of the case. The firewall had dimples where I needed to drill the new holes so that was not a big deal. Where I ran into issues was when I went to put the belts on the compressor. I think I pulled this stuff off the donor car back in 2004 and though I did take pictures of lots of the unit as it came out I did miss a few things. I never gave it a thought at the time about how the belts ran. Being that it was a 3 grove crank pulley I just assumed the the grove not being used ran the A/C system. Not so I found out. This is also a California engine so it has the air pump also to add a little more excitement to the puzzle. Oldkayaker helped to solve the puzzle when he posted the picture of the belt arrangement. That is when I discovered that Ford changed the crank pulley for A/C. I was able to locate a NOS A/C pulley from Green Sales and what I thought was going to be the correct crank pulley from a Ford dealer in Texas. That pulley when it arrived was incorrect. The engineering number matched the parts book but the actual part number I did find on the pulley was not correct. Who knows what happened 40 years ago when that part was first put on the shelf. Since I was not having anymore luck locating the correct pulley I finally mounted what I had in the lathe and cut the grove from 1/4 inch to 1/2 inch. Thankfully the pulley was cast iron and had lots of material to remove. I also have a 3 grove press steel pulley that came off the early 74 (Sept 73 build date) parts car that I have. There would not have been any way to modify that pulley. So that part of the restore is done. I am still a few months from firing it back up so I can recharge the system. I have pulled a vacuum so it will be interesting to see if that holds until I get back to it. When I pulled the system years ago it still had Freon in it so I would think unless I messed up an o'ring when I went back together things will still be fine.
