just doing my mk2 vitesse using std 4cyl type nine and parts from Canley classics (bell housing adapator ,propshaft and spigot bush ,depending on if you want the gear lever in the same place you then have to cut off and reposition the gearlever mounting which means stripping box down(not to bad to do yourself) and having it welded back on (alloy which I had done by a friend) it can be left as it is which is in quite a nice position but the hand brake lever hits on the back part of it ,you then have the issue of carpets and cutting or moving the lever.The type of box used probably depends on power of the engine the 4 cyl should be good for 150bhp but after that use the v6 version but you have to modify the input shaft or you can get a shorter one fitted from the 4 cyl type.
