Hey supratruck,
Marlin says that this can be done, but only if the transmissions are no newer than 1995. It must be a pre-96 because after 95', they changed the helix angle on the constant run teeth and made the input shaft 3/4" longer.
So in another word, early (1986-1995) R trans can not be interchanged around with late (1996+) R trans.
Good luck!
