this is just my opinion but i would given time and space tear out what you want - label everything and take photos - cheap insurance....and set it out,make repairs, adjustments...take out your current gear out of your good shell and then swap...if your up to the "challenge" of teh swap then any little gremlins that pop up you more than likely can solve no problem - i have helped a few friends convert over volvos, corrados, MBs, and a host of american cars...as long as you have more than you need (in your case whole car -excellent) you should be fine.

our easiest was a 84ish volvo sedan in great shape - went from NA to turbo from a rotted out wagon, no problem.
