8-3/4" Housing/Axles & 489 Case

Would a c-body rear axle need a lot of modifications to fit an A-Body? Asking for myself and anyone else that might be wondering.

Yes, it will need to be narrowed and spring pads relocated.
This would be great as a base for a drag car, or narrowed more than stock rear.

Case is the strongest (1-7/8" pinion) produced, so that is good too.
