8 3/4 swap

[Robin House]

hi guys, I want to swap my 8 1/4 out to an 8 3/4. I can’t find one from an A-Body, wondering if it’s possible to install one from an E or B body. I know they are wider but what’s the biggest issues I would have?

'68-70 B will fit '67 to ? A-bodies, just remove the perches & weld in new ones.

They are 44" OC & the As are 43" OC.

The differential is a bit wider but will still typically fit with stock wheels.

It's been done, pretty sure there are more desirable B-body years, but I think most will work, other than moving the spring perches in a little, and possibly having to shorten the driveshaft, maybe u-joint, and wheels. Not all that bad of a swap. Do a search on here, I know a few members have done it.
