8 3/4" or Dana 60?

Being you are going to weld new ends on it anyway you can use any dana 60 being they all have 3" axle tubes. The dana 60 has spline counts ranging from 16 to 35 so you have to look. Being you are going big inch big block 35 spline is what I would use. That Moser 60 will be a good piece.
