I picked up the Transmission and drive train from the wrecked 91 200 yesterday. I will have to be storing them outside in order to remain married. Any words of wisdom on storage? Ok to wrap in a blue plastic tarp? Can I seal the unit or should it "breath"? Also the Allen bolts on the drive line are frozen hoe can I easily get these out with out damaging things?
