What did my truck look like?

[Vicente Aceves]

I just bought a 74 GMC 1/2 ton shortbed pickup.

The previous owner had it for about 15 years. He bought it the way it’s painted currently.

The SPID says 556 Grecian Bronze/White
B85 Upper Custom Mldgs
Z62 Custom Deluxe

Can anyone tell me what the “White” part of the 566 code means? Was it the roof originally?

I’d also like to know what the Upper Custom Moldings are?

And what did custom deluxe get you originally? I know it’s a lower level trim. I just don’t know how “base” of a trim level it is.

Any help is very much appreciated!

Thanks Vinnie
