I know there are people who put the 1.9 tdi into all kinds of stuff, check stuff for suzuki samurai's thats a very popular one and you may be albe to use the transmission out of it, from what I have seen it has a divorced transfercase. and Im not 100% sure but I think most VW bell housings are the same so you may be able to use 1.6 also
