7.25 rear end dimensions

It's been around forever, and some of the measurements line up well enough for folks to think it's accurate. Especially since most folks don't usually have all of those different measurements. I can't confirm most of the 8.25 or 9.25" measurements on the chart, but I know for a fact that it's completely wrong regarding the A-body 8.75 and B-body 8.75's if you consider that entire year range. It doesn't list the C-body 8.75's at all, and doesn't give a different measurement for the Imperials, which are different.

I have posted this list for awhile, I'm pretty sure I found it here or another of the mopar forums. I've added the F-body measurements as they came from a trusted source, and as I mentioned I've been able to confirm myself quite a few of the measurements listed, and all have been spot on so far.
