New axles too short?
I had the same issue a few years back. The issue stems from the fact that no A-body 8-3/4 came with big bolt pattern brakes and the way that the axles are measured (from the outer flange to the end of the splines)
SBP A-body brakes used a 1-3/4" wide drum, but BBP brakes used a 2.5" wide drum. The axles have a different offset from the wheel bearing to the face of the wheel flange to account for the wider drum. But since axles are measured from flange to spline end, if you cut a BBP axle to stock A-body 8-3/4 length, the axles will end approximately 3/4" short of the normal position.

Brake shoes help (8 3/4 BBP)
The measurement marked Axle Offset is the difference between the two.
