it makes no difference at all what you choose, the 12 bolt is marginally lighter and has the advantage of the slightly higher pinion and accepting gm brakes.. z06 and "ls1" brakes.. but a fab 9 housing weighs the same, costs the same and 9 inch carriers can be bought to accept both 12 bolt, ford 8.8, 9 and 9,5 inch difs and gears.. and can be spec.'ed to accept both ford and GM brakes, so its a matter of preference...
