You can mount a Alpha 1 to a Gen.II bellhousing, but only after you swap all of the shift linkages to gen.I, 'n the oil fill port would have to be plugged, or you could swap in a Alpha 1 bellhousing(I think), but then you've got a gen.I, 'n it's no longer a Gen.II, which is still current issue,....
I've never tried it, but spent several hours talkin' 'bout it with a super good Merc tech, years ago,.....
We came to the conclusion, that it Probably could be done, but why the 'ell would you,.....
Ayuh,.... Ya gotta drill 2 more holes for the Gen.II,.....
