Not really what you are looking for, but I have put a ton of small diesel drive trains from 80's-ish cars into Classic american/Japanese/European cars and my method has alway been
1. Put new drivetrain in loose
2. Support at appropriate hight
3. Cut holes in body to clear new drivetrain if necissary
4. Bolt new engine and trans mounts to new engine/trans
5. Use C.A.D. Cardboard aided design to fab up adapters to mount new engine mounts to old donor body.
6. Make hybrid driveshaft/s from engine driveshaft and body driveshaft. (If you are not a machinist have a driveshaft shop do this for you, the tolerances are pretty tight)

Unless you are an electronics wizard I would recommend that you start with a less electronic swap. That being said, I have learned a ton by just starting a project I was very interested in, even though I did not have the skills, and just dealing with the problems as they arose.
