I've not had a chance to put a lot of miles on my new tailshaft seal, but it appears to be a winner! I was worried when I first got it because the factory unit didn't have the extended rubber cup at the end; it was just flat. Would that cup bang into my driveshaft and tear itself apart? Nope, there's still enough clearance that everything appears to be fine. The photo shows the seal this one replaced. I think it's the factory unit from 1959, and holy cow, that thing didn't want to come out.

#1... Made on the USA! Didn't think Amazon allowed USA products to be sold on their site. #2... Perfect fit for my 65 F100 3spd trans output seal
