if you can find a supra front cut (cressida will probably do fine) then it wont be very hard, wonder if the car will be registerable in your case as there is a chance that you'll need to slightly modify your firewall
This depends a lot on what you pay for the parts. I really don't see a need for a front cut, there aren't that many parts needed. BTW I've got most of the parts needed for this in my 90T parts cars. The only thing I won't sell right now is the tranny/slave cylinder/flywheel. PM or email me if you are interested.
