From Utah. 67 Barracuda Fastback. Hello!!

Rick. This car also has a lug pattern of 5 on 4 1/2 on all four corners and disc brakes on the front. Manual brakes and Manual steering. I was under the impression that the A bodies had a smaller lug pattern. It also looks like the axles in the rear were changed out.

It would have had the 4" for sure. You'll have to determine what mods have been done. Could be a chance that rear came from a early B body? Who knows since there's some non stock things going on. It will surely help when you can get the picture thing working.

One thing we do know is you blew up a 8 3/4" rear with a 340/Auto car.....You're a animal pops. :D:D:D

Seriously, plenty of good help here to get you the info and parts that you need. We'll all figure it out together.
