I could use the 89-91 housings and just swap the front cover for the 12A one? Someone told me that 85 and earlier housings wouldn't match up with 86 and later housings. That's the reason I was using all 85 and earlier housings in the setup.
I think I'm just going to try and get a 4.3 diff, I was to go with more than 4.10, but it sounds like anything above 4.3 is to much.
