Throttle body plate no, I had to have a machinist do this for me, as it had to be thick ally (ie 3/4inch i think we used?) and this couldent be ;laser cut.

I can do the mild steel adapter plates, they come with the zetec holes and the ports cutout.....however the holes for the Rover inlet are not present, as there are two types of manifold (M16/T16).....and/or welding it onto there, so you'd have to sort that bit yourself
