No, its not a direct bolt up swap.  The transaxles are a
variation on a design and you could say they are cousins
but not twins.  Some people have done this but it does
require some fabrication and modifications.  What you
might consider is selling the '80 091 gearbox and buying
a good used (good luck finding one) later watercooled
Vanagon 091-1 gearbox for the interim
