I couldn’t stomach the way overpriced D&D set.
I’m trying to track down the info on the parts I ordered from California (they are in the car now). I think the gentleman’s name is Richard Gordon from California Classic Clutch. He just had me count teeth and whatnot. Ring gear count should be 156.
It’s a newer style GM set that fit perfectly! I bet the one’s from ebay will fit too. I wouldn’t bother with used.
