Guilty! I had a couple of pairs of these Fulvia S3 seats retrimmed with black velour cloth (they have obviously faded with the passage of time) facings in the eighties. The head rests are indeed early Beta coupe, they are a straight swop for the original Fulvia ones, but are a much better shape, pity Lancia didn't do it themselves! I sold both pairs in the early nineties, I wonder what happened to the other pair?
