I've used these later pinions in the 30/31 axle in the past, just had a good engine machine shop with cylindrical grinder reduce the pinion diameter to 1". Not sure whether it goes through the case hardening or whether the pinion is through hardened at that point but I usually assemble with Loctite to stop the dreaded "shuffle" of pinion support components.
