18 spline A833

Im foound an 18 spline A833 locally, its out of a Charger with a hemi. As far as i know the input bearing and retainer are different than the 23 spline units, as well as input shadt diameter, output shaft spline count, and internal differences i dont care about as it pertains to my next question.

Which is: what all do i need to put this behind a 360? Can I machine a 23 spline bell housing out to 4.8 and use an aftermarket clutch/pilot bearing? What clutch fork and Z bar will i need for an A body? ('66 dart)... im expecting to have a sriveshaft made, and i will have to find shifter/linkage... am i missing any other external differences that will bite me in the *** (and wallet) while bolting this thing up and dropping it in?
Tailstock from charger is to long for A body
