gotcha. now that i'm looking at it closer i think the roof skin swap is probably less work than welding in a filler piece for the removed sunroof glass, especially since it probably has a curve to it that would be a nightmare to match with my limited tools. Have you considered replacing the seats? lots of weight to be shed there, and i am hoping you can help us find a proper way to keep the airbags working properly with the JDM Euro R seats in a USDM TSX. Best method i've seen so far is gutting a stock passenger seat and hiding all the sensors the TSX is looking for.
