Thanks you for this info, that's a big help!
I found out that a lot of a-bodies between '69 and' 72 have a 8.25 diff as well as the right, 5x4 bolt circle...
No, you didn't. The first year for the 8 1/4 in a A body was 1973. What you found was bad information. The 8 1/4 never came with the 5x4 bolt circle.
Now, having said that, all of the information I just told you is regarding AMREICAN made vehicles. Regarding vehicles in other countries, you could well be right. That's information that you should share where you found it. That would be a good addition to this site.
