Are you talking about putting F/G door cards on std doors? The reason I ask is that my F/G door internal was flat and had a flange so the doorcard would sit flush. On a std door you would have to have a moulded section which followed the contours of the door innards, especially if you intended to use the std interior trim pieces such as door pull etc.
I would say this WOULDN'T be straightforward on a road car, especially if you were looking for a reasonable level of finish.
I have one off dry carbon door cards which marry up to the original fixtures. Just wondering if they would match up to FG doors for added lightness!
