8 1/4 suregrip and gears

Closest one out of an 87 I can find is an hour and a half away and they want $250 plus another $50 for a core if I don't bring mine in.

I will check on the dana and see what I can find. Broaden the search if you will. I watched an episode of Hot Rod Garage where they built a rear end and it looked like rocket science... or at the least I don't have the tools to measure the depths I need to hit. They didnt show the preload portion so I'll need to google-fu that.
