I think that the input shafts are different. -1 takes a Chevy fine spline clutch disc and uses a Chevy nose bushing.
I think the shift shaft connection is different, i.e., more primitive than the -2.
Different bellhouse as well.
Inquire with Bosswrench. I'm pretty sure he can give you the specifics that you need.
I think you will wind up swapping out parts from a -2 to use the -1 as a bolt in to the Pantera?
