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".

I have a slant six car and am changing to v8 car with 8.75. 8.75 "A body" rear end is currently sbp, changing to bbp. I'm trying to figure out backspacing for wheel without converting to bbp and disc setup and the having to possibly cut axle down. I want to run 6.38 BS. Car is completely torn down, going to mini tub and cut lip of rear quarter and possibly roll. Also have 3/4" shackle offset. Want to run a 295/40r18. Any help would be appreciated
