Did they make 5x4” axles for 8 3/4 rear ends?

Memories
Back in the 80s when we wanted to put an 8-3/4 rear with the LBP, large brakes and discs up front we used the rear out of the 66-67 b-body and a-arms/discs from the 73 and up a-bodies.
The 8-3/4 a-body rears were expensive and as noted had the SBP.
The 66-67 b-body rears were roughly 2” wider and we used those offset rear shackles which fit the roughly 1” per side offset. It wasn’t perfect but the setup sure made my 71 Dart Swinger with a 360 (upgraded from 225) really, really fun to drive.
