hi looking for support on upgrading the old 82 hj60 2h from the OG 4 speed box to a 5speed. I have sourced one from a 88 2h troopy. my main question is what other parts ill be needing. will my bell housing fit? and do i need to get a set of drive shafts out of a 5speed 60 to fit? and light on the subject would be appreciated .
