A-Body 8 3/4

Looks like you found yourself what most A-body folks are looking for. A complete drum to drum A body 8 3/4 with the 4 inch (standard early A drum brake bolt pattern) and unique to the A-bodies. Easily converted the 4.5 bolt pattern with replacement or redrilled axles/drums.

The factory 440 combinations with auto trans all had 8 3/4 rearends standard. With a good gear selection, and Sure Grip center section, you will have no problems with an 8 3/4. You will break a standard axle before you hurt the center section, and that will take some horsepower.

Great rearend....in your described engine combo...you do not need the Dana 60.

I am sure there will be many members who chime in on this one.
