Quick one, rear end width.
I like the 73 up A body being narrower then our early A bodies, I just learned this not long ago .
That part is accurate, A-body rear end widths were different for the 7.25 for different years, and the 7.25 and 8 3/4 were different lengths from each other too.
But there's a TON of inaccurate info on that chart. Like, B bodies. B-body 8 3/4's were NOT the same length from "62-70" as it states, not even close.
This info is just for 8 3/4's, but it lists everything and all of it is accurate. I added the 8.25" rear info that I had on F-bodies.
