the a body rearends are wider but you can make them fit with different wheels and control arms. Does anyone know how wide a b body rearend is? Also the main thing is will it bolt up.
No you can't use the B-Body rear under a G-Body.
Depending on the year you might be able to use the carrier.
1987 and older are the same 28 spline axles.
1988 and newer use 30 spline axles.
