The Stovebolt Site Forums The Shop Area Driveline Transmission seal

I was able to get clear of the transmission and got the ball housing off. Now, I just have to pull the floor pan out to get to the dowel pin that needs to be drilled out before I can remove the old seal.. (Photo Attached) It looks to me as if this has never been touched. It seems very improbable, but I don't know much about the trucks history. Apparently it was from Oklahoma.
It was my late Fathers project and he gave it to me when he didn't drive it anymore. I promised that it would stay as stock as possible.

Thanks for the advise and tips.
From me and my Dad
Parts ordered.
Have a good Memorial Day
