993 TT wing mod, help needed
 

I'm looking at buying a 993 TT that has some extensive mods, one being a larger intercooler, as such the rear deckild does not close flush with the body.

It gaps approx an inch and the decklid latch has been modded to ensure it currently closes.

Should I buy this car and not want to play with the mechanicals, is there another wing that would suit, is the RS wing dimensions identical to a TT internally ?
