I got my old '88 back from my brother... with the rear end out of it. I'm trying to get it ready for Harlan, Ky Memorial Day weekend. I opened it up and the spiders are shot. I was thinking of putting a spool in there, but cant see how to get the side gears out because of the two rods holding the mechanisms that work the limited slip? Can you even put a spool in the G80? Could I swap it out with a carrier from an open diff 10b? I'm just wondering if there might be a cheap fix.
