I have a 55 1st series 1/2 ton, and I just aquired a boat, When I brought it home
and attempted to back it up my GRAVEL driveway, I met with wheel spin on the
right side. Does anyone know of a posi or locker for my truck? I talked to a friend
who does rear end work, and he said I might try putting in extra thrust washers on
the side and pinion gears if possible. Any help out there???

Thanks, partst
