NOS Door/fender emblems are still around...The trunk lock cover is tougher to find...Don't go by Ebay pricing or condition on Gran Coupe parts most seem to be smoking crack with the craziness..."Good" condition is in the eye of the beholder I guess...
Year One had some trunk emblems repoped years ago and there's some of those that turn up from time to time...The trouble with those is the casting material was too soft and the spring mechanism gave it up within a short time...Y-1 had a big backlash of them coming back but some escaped...So watch for those as "NOS" pieces...A quick tip-off with those is the outer perimeter of the emblem doesn't have the textured argent treatment...
Note that the emblem did in fact have the clear acrylic "lense"over the painted surface of it like the other badging...Most used pieces you find will be missing it...
And for your viewing pleasure here's an NOS emblem that sold a few years back...
