Rebuilding this 12bolt. New spider gears. Problem is gears won't fit with the shims/thrust washers, seems they lock the gears up.. now if I remove all 4 then she goes together an spins like it should no problem.. talked to a old timer an he said it would be fine to run with out said shims if there ain't any MAJOR LOOSENESS AN from what I can see there is very very little move me to. (trucks just a cruiser stock 230ci an 3 on the tree. Is he correct?? I can't seem to get a right AWNSER from anybody. Had this problem in a old d30 for a wheeler an ran it with out an never had a problem..
