I'm researching this at the moment, I'm convinced there will be a lecky drive that will fit directly in place, my mates loaning me a type 9 speedo drive, as these can be got cheaply in lecky drive, to see how similar, if not from what I've seen can be modded easy, I'm doing this for myself, even if it means machining a adaptor boss up, but with that being the case it will be defo easily possible.
I'm certain there are some GM T5's that fit.
