Yes! I found the gaskets on RA also - the listing is for a '69 C30 pickup. The H110 was available in that chassis. The FelPro pn is FEL-PRO RDS5049
So I ordered all the parts - a new pinion seal and the felt, gaskets for the center section and two new axle seals. All of it from Rock Auto for $32 delivered. Great score! Thanks again Andy.
