I see you've done your homework.
You're looking for a unicorn, I'd suggest that you restart your search in
South Africa.
It is my understanding that they made complete type IV engines until late
2001.
The fellow down in Houston that sells the Tiico conversions had some
complete engines for sale, not NOS but New Inventory about a year ago.
(Please don't hesitate to correct me on this .......... It came to me as
rumor from the Vanagon List)
