Bought a Tru-Trac for my dana 30.........i know i know......shoulda just put a cut down D60 under her But im no guy for settin up ring and pinion since that is also new, but the dude settin em up ran into a bit of a problem. The Tru-Trac has holes for the ring gear bolts drilled at 7/16"? or 1/2"? and the ring gear bolts are at 3/8".........this leaves a lil bit of slop IMO........called Detroit and they said thats how its supposed to be and they have been making them like that for 2+ years and i shouldnt worry bout it. My only ? is under hard abuse will the bolts shear off due to the slop in the bolts holes? And would it be ok to make a thin sleeve to put in the bolt hole to take up the slop?
