I`m going to look at a gear set today, waited long enough to convert to a 9 inch, the guy has two third members 3.00 and a 3.25, both tracton lock 31 spline, question is don`t think I would notice any appreciable differance between the two would I, already have a `58 inch big bearing housing from a bronco, got one left side 31 spline axle, still need to buy the right, also looking for crown vicky disc set up. Things take time when your a penny pincher,
