Hi Joe,
I've had a pair of original, black, front seats sitting covered on a shelf here for a few years. Out of my 71, post-mod. Original, straight, but not perfect. (I had always intended to keep them with the car in case I ever rolled it back to original, but I'm feeling heavy in preparation for a move, and my conviction is wavering. )
Glad to discuss further if they might meet your needs!
I'm up in PDX for now... though our buddy Chad is pushing hard for a move South.
