Gord, those quad mirrors almost look like dual spotlights beside the addon west coasters - yes rare!
Fumblin, that trim on the door [correct placement] makes it a "CST", or Custom Sport Truck option [should be on both doors], which would fer starters be a big window, also had that trim down the side 'feature line', and chrome bumpers, as well as widgets like cig liter, bright trim on dash and gas pedal, fancy carpet and seat - lower production, so worth more, if yer puttin it on e-bay
