Ok, thanks for all answers and support "techie". Here is my problem.
I have a VX220 Turbo that i wanted to have a more cupe look on and possibly an improved engine ventilation as a side efect. Said and done, I contacted eltech-italia.com for thier rear bonnet. They did not inform me that they were to manufacture a bonnent only fitting the NA version of the car but that was what they shiped and I recieved several months after agreed production and delivery time. I have of course documented the missfit and mailed them about this, without response so far. Well I hav only nudged them yet once in this matter, second time will be after this posting. Since their website/ facebook site nor the representative I have been in contact with ever mentioned that their bonnet only fit NA i feel a bit frustrated. Maybee they have a turbo version and this is only a matter of wrong shipment, time will tell. But if not, then the question is how to handle the problem and maybee fitting a NA clam ditching the boot could be a way fwd. Otherwise .....
