I ask some question to Jeff Kerr @ www.acmeadapters.com and here is what i got.

"Originally these adapters were used in our suzuki applications for use with
the 22R 4 cylinder style transmission 1979-1996, then over to toyota trucks.
At this time we only have the basic kit to mate the VW engine to the toyota
transmission, you will need to fabricate the other bracketry as needed. Some
have found less fabrication is needed by using the Acme engine mounting
brackets from our sidekick/tracker application and only fabricate the frame
side of the mounts. This kit enables you to reuse your original style toyota
clutch set and starter. The clutch used with this kit is the earlier model 22R
toyota 8-7/8 inch disc.

With this kit you receive the adapter plate, machined toyota flywheel,
selflubricating oilite pilot bushing, bolting hardware and instructions.
These sell for $575 and includes shipping to USA addresses.

There have been a few of these done, mostly in pickups and most seem happy
with it and are using the Canadian 1.9TD AAZ engines. If you are wanting to
use a TDI they are a bit more complicated than the earlier model diesels
due to VW's immobilization and wiring. "
