My 72 Blazer was filling the 205 transfer case with automatic transmission fluid. I replaced both seals and the O-ring. The coupler slides over the O-ring on the input shaft of the transfer case. I believe the main problem with mine was the O-ring. Someone had put silicone on the splines and when I tried to remove the O-ring it broke. The O-ring was hard and brittle probably 40 years old. Hope this helps.
