I need the NAPA part number for a 10 bolt drive shaft to a 12 bolt rear-end.
You probably don't need a conversion (bastard) joint. If you were going from a 10 or 12 bolt to a 14 bolt then you would need the Napa 447. I put a 12 bolt in one of my trucks that had a 10 bolt in it & they both used the same joint.
Thats how my trucks were anyway, but you might want to double check yours.

bigmack is probably right, but just in case its either NAPA #348 or #447.
