you just need the hydro bits off a 16v or a VR6 mate, basically the secondary cylinder that joins to your pedal box, the pipes that go from the brake fluid reservoir bottle to the top of the gearbox, where it meets another cylinder.. you need all these bits
i have no pics at hand
if you look on your 8v reservoir theirs a little pipe poking out the right hand side (as long as its not a very early GTI) this is where the pipes join the bottle
if your car is a J, K or L reg you need more parts like i did for mine
screech the seat thing u mention is a hydro to cable conversion thing and in my opinion its crap, we have fitted one in the past looks ugly too
just means you dont have to fit the hydro bits
