RE: '70 challenger western sport special, rare?
Western Sport Specials were mostly an appearance package (A91) It consisted of a vinyl top, pedal dress up kit, belt moldings, wheel well lip moldings and a few other things (and the Western Sport Special Applique`-DUH!). I don't have any production numbers off the top of my head, but its a pretty rare bird indeed. Sales were limited to Southern California and San Francisco regions, beginning in the fourth quarter of 1969.
One Trans Am is reported to be a WSS-T/A, but its most likely a dealer conversion to get it off the lot (I think the thing was in New York anyway). Lots of the trim pieces were common with both packages, so it wouldn't be difficult to slap a WSS decal on a T/A...
