NP203 Seal - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm trying to find the seal PN# for the tail shaft of my NP 203 at the yoke connecting to the drive shaft. I've been to the local Napa auto, and O'reilly's and they both can't find the seal. Napa kid even asked " What is a transfer case?". So any help would be great.
