Looking for a timing cover seal for my 1962 GMC Suburban 305 and after ordering two using the number on Rockauto that were incorrect. I thought I was having trouble with CR vs SKF part numbers, but I think rockauto listed the part number for a straight 6 under the 305 listing.

I found the Felpro timing set part number, called Felpro and they said it was a dead number but I had them give me the seal number from that set, and it was a dead number also, but he crossed it to National Seal. The National number is 480574H OD 3.256, ID 2.375.

The obsolete Felpro timing set number is TCS 12937, and the crank seal in that set is P90931.
