Here is a good Hemmings article on the 8 3/4 with widths and some of the things to look for.

Thanks, Kiwi, but I believe that is the list in which I had to start with, But I have a 50 so they didn't have my year, cutoff in 48.

Also, thank you on the Hemmings motor news, that is a very helpful artical, and gave me a lot of much needed info. appreciate it!

Are you looking for overall length or axle length? I think there's a table in my Hollander manual on axles.

Measured my '46 Dodge to find the easiest mopar 8 3/4 swap, just took 2 straight edges and a tape measure: Spring perches 47" center to center and track 62" (from the face of the 2 brake drums). Closest fit is a '71-'74 B body. The track is listed as 62" (although mine measured 62.5) and the spring perches are 47.3" center to center. The perches are wider than the original springs. It's easy to shift the center hole over ~1/8" on each side with a grinder and a little MIG fill in. I will either use a spacer to take up the additional perch width between the U bolts and the original springs on each side or redrill the perches so the U bolts will be tight to the springs. Seems even easier than cutting off, repositioning and welding the perches, then cleaning out the axle housing for the cooked lube creating by the welding.
