Transmission shift lever leak solution

['69 C10]

I just found this solution to my transmission shift shaft leak problem. The seals have two inner seal contact points with the shaft to help prevent leakage. Also, the outer surface of the seal is rubber to make up for any damage/imperfections on the outer circumference surface of the transmission case. Hope that makes sense. If you look them up, the seals are supposed to fit a large number of GM transmissions. My tranny is a 2004R

Anyway, after a couple of longer test drives, my pesky leak seems to be solved!
I bought mine off of ebay. Pack of (5) seals for $30.

Anyway, thought it might help someone.
