How hard is the rebuild on this tansmission and transfer case. I am trying to save as much money as possible so I can get everything done to get my blazer back on the road. When I parked it, the tranny and t-case both worked, but were leaking some oil. I want to rebuild them before I swap in my rebuilt 350. No sense in taking it apart twice. Also, on the Hydro conversion, does it matter what year the clutch parts come out of? Does it need to be a second gen, or will 88 and up Fullsize parts work?
