12 bolts arent much better than 10 bolts.i blew 3 of them before switching to 14 bolt ff.and i only run 35 inch tires.but free is free.like i said,if you can find one,a 14 b semifloat will be a lot stronger and still give you 6 lugs to run the same wheels and tires you have now.and should also bolt right in with no modification.
