hi id like to know wether you can use Passat syncro rear diff etc with a prop connected to a o2m transfer box, as im trying to weigh up my options with converting my mk2 vr6 to 4wd, I want permanent 4wd rather than half hearted 4motion, im not too competent mechanically, but some friends are. have no objections to cutting the boot floor out and putting a flat floor. would like to know what is best??? cheers Ben
