Cool truck!!As far as axles they are a 14bolt and dana 44.I have never seen a 60 on a 3/4 chevy stock only on 1 tons.Most 3/4ton 44s are strong than the 1/2tons though.The housing are thick and less prone to bending.Blazin <IMG SRC="smilies/biggrin.gif" border="0"> <IMG SRC="smilies/usa.gif" border="0">
