Google ellisautoworks in FLA. They do VH swaps for around 6500 IIRC. Otherwise you're on your own working with a local shop with probably 0 exp in VH's. Also you need to get on Nicoclub.com. You can pick up a lot of info there too. 5sp Z32 adapters are available from Maxworx and Elwesso on nico is in the process of making adapters as well.

It's worth it though.
