    they both suck... 10 bolts just suck worse. do yourself a favor and pick up a 14bff. 3/4 ton applications are a direct bolt on.

    nah, that thing should have a 14bff, or maybe a 14sf, but not a 12b

    10 and 12 bolt are about equal in strength....at least with the 30 spline 10 bolts. 10 bolts pinion is a good .3" thicker than the 12 bolt.

    About the same. Go for the 14FF. Can be had for $150.00 just about anywhere.
