Driveshaft alignment will play a big role in wearing out that tailshaft bushing....even though you have u-joints on both ends that short driveshaft has got to be darn near straight-on. I had to grind the aluminum tabs off the side of the tremec so it could be re-located....also had to re-drill the transmission cross brace. I can bet you this is your problem....thrust bushing. I put 3 rear seals before I found this.
