I am looking for a source for the fitting that presses into the transfer case (NP205) for the vent extension, or an alternative to the factory fitting. Local transmission shops and parts stores do not have anything suitable. It has been suggested that I cut threads and use pipe fittings, but the transfer case is assembled and installed. If I were to unbolt the output housing(?), is there anything that would prevent me from rotating it enough to cut the threads without dropping metal shavings into the transfer case? Does anyone have any other suggestions?
