Thanks, Truckernix. I was able to obtain the drum. As you say they are super rare. I got it primarily as a back up and will just throw it on the shelf. Keeping on the lookout for another.
I am keeping my truck entirely stock except I made the change to a 4.10 rear end. There sure is a big difference now and it is nice to be able to go around 50 or a little less and not a max speed of 42 mph.
More out of curiosity than anything I did discover a place in Illinois that resleeves old drums. It is nice to know that is an option too.
