Ok so I had to replace my np208 in my 85 K10 which is a 4spd. So after I picked it up a I stopped at my local auto parts store and asked about a gasket for the t-case. They told me there wasn't one so I went home and installed it. Then someone told me there is suppose to be one between the 208 and the adapter. I let for Maui for a week with my K10 in my shop and when I returned I had a quart of fuild on the floor from the transefer case and it looks like it leaked out of the front where it bolts to the adapter. None of the auto part stores I have contacted in town can find if there is a gasket. So is there suppose to be a gasket between the 208 and the adapter? Or could my input shaft seal be leaking up there?
