An accurate 8 3/4" rear axle width list

Ok, so, I've posted parts of this list a few times, normally in response to some of the really inaccurate charts and lists that are out there and posted too frequently. It's not my list, I sourced it from the internet but I can't remember where. Since the time I downloaded it several years ago, I have personally confirmed a bunch of these numbers. The A-body numbers, the E-body numbers, several of the B-body measurements, a couple of the C-body measurements, and even the D100 measurements. They've all been spot on, so I have no reason to suspect any of the measurements I haven't personally checked.

Everything is for 8 3/4 axles with the exception of the A-body 8.25 and BBP 7.25 measurements I added myself, and the F-body 8.25" measurements.

I also added the A-body BBP 8 3/4 width, that's for an A-body housing with axles that have the standard BBP axle flange offset and use 10x2.5" or 11x2.5" BBP brakes. It should be accurate within an 1/8".
