Need some help. On my 1990 Chev. SS, trim tag located under the cowl on the firewall, there is a series of codes and numbers. L19,YE9, KC4, etc. I know these are options on the truck. But on the very first line of the trim tag is the following:
R2109172 90 1 122473, I know that the 90 and the 1 is the Jan. 1990 production date, does anyone know what the other numbers mean? I was told that the series beginning with the R was the end of the VIN number. But that doesn't match the VIN on the truck. Possible problem there? Please help if you can.
