The WSS package was offered on 70 Challengers sold in CA. It was a dress-up package, not a performance thing. It included the woodgrained non-rallye dash, front valance, belt and rear finish panel moldings, front & rear bumper guards w/ rubber inserts, pedal dress-up, a rimblow steering wheel, a vinyl top and every one I have seen had A/C.
It's A91 on your fender tag or b/c sheet.
The woodgrained dash also came in Gran Coupe Barracudas and I believe it could be ordered on its own.
Barry?
