im swapping my rebuilt 373 ring and pinion into a 2 wheel drive coil spring rear that has a tired 410 setup. when i pulled the pin out the spider gears in the posi moved and i cant get the pin back in. should i just tear it all the way down or is there a trick? nevermind, i lined up the spider gears with a c clamp. the diff is in the shop because i dont understand preload or setting up the gears.
