If we are talking about a 40 series 4 speed transmission... I have at least one sitting in the barn you can swap in for a $$$ donation to the club.
Full disclosure... No idea of the history or condition of it.
Boys have been getting more bmx focused of late, so got this hitch mounted bike rack installed. The 4x4 labs swingouts clear for now! Will have to rethink once I get my spare mounted though.
