67 SPID help

[cj847]

I recently picked up a 67 Chevy C10 that appears to have had a significant restoration in the 80's-90's. So, some of the badging and trim has been removed. I am trying to figure out what it looked like originally.

The truck came with a chrome front bumper (4V37AD) and side trim (4B98AA) (which was removed in the repaint along with any side emblems. Also the truck has the panoramic cab (4A10AA) with chrome trim around the rear window. The front window does not have trim, so I am guessing it was destroyed by impatient removal.

Anyway, They painted over the grill trim. I am trying to figure out if it was chrome (without removing the paint). I actually sanded a spot off underneath and it appears it was painted white (or grey primer) before blue.
Does anyone know what these custom groups were comprised of? I would think the trim was chrome seeing as the bumper was chrome.
