I did this. But I had a diesel vanagon and a rabbit Gti as the donor. As long as
the vanagon is water cooled there are no significant differences. Here is a list
of diesel parts you will need:

bell housing or whole transmission

diesel oil pan

diesel oil pump pickup

diesel flywheel/clutch

diesel engine mounts (alum castings and steel tube)

diesel exhaust manifold (can make up custom or use twin tube dasher)

I used the diesel exhaust manifold and the stock diesel transmission. while
these are not the optimum parts it did get the job done is only a week end.
Getting the fuel injection stuff, electrical and plumbing took another month.
