is there enough spline left when using the adaptor plate for the clutch disc?
one can get a clutch disc seperate. I did just get an 11" by itself. there is a tendency these days to buy a clutch kit assy, that is ok if it is for a std install, but this isn't.
you do not require another crossmember as he stated. that is just like someone wearing suspenders and a belt at the same time
