Hi has anyone got any idea of doing a rear wheel drive cossie conversion on a mk4 van? I've seen a few done in cars but rarely in vans? I want to run sierra cosworth engine and running gear but are stumped at actually how it is going to fit. I am presuming that i need the floor pan from a sierra and such like but thats about it! Any info and how much i'm looking at to do the project will be great thanx!!!
