what axle hang out did you order . a bodies 8 3/4's were different than the others . if you ordered them , how much from the housing to the axle hub are you getting .
True, 90% of the aftermarket axles use the full size flange offset, but there are a few that still offer the 5 x 4.5 in the A body offset, and want you to redrill your A body drums... So, OP, we need to know which axles you ordered.
