yanno, I looked all through out my manuals illustrated parts, service manual, fisher body manual et cetera ... (and the 81 color chip and fabric folder - yes I have one) and there is no mention of a GM paint code or part number for wheel argent. I looked around the net and found several companies that make finishes for rally wheels but these "Silver-Argent" colors are way too light and bright in color. Having only seen ONE set of Argent N78s in my life .... I imagine painting them in just about any "close" color would go completely unnoticed. Ask any of the guys with a 442 that have perhaps had their bumpers refinished. That "argent" hue seems "right". Most other GM alloy wheels I've seen (i.e. IROC rims) used a charcoal insert ... this is way too dark.
