what would it really take?

I agree with the posters above. Although initiallly it appears a simple job, the number of parts, and their cost to track them down, ship them in, and install them would make it not feasible. Especially true at the selling price of the car in question, in which you are paying mainly for the existing drivetrain.

For around the same initial price, you probably can watch these boards, find a nice clean running, driving, licenseable car, and still have it shipped your location.

Good luck on the project, and nice to see you have your son involved!
