I cut a set of those mirrors off one of my 1-tons. Mine were scrap quality, not NOS. As for GM accessories I have a Hydra-Matic 1-ton truck but otherwise the accessories on mine are common aftermarket stuff (and be worth removing) that might be found on any truck.
I have a factory GMC radio that came with one of my 1-ton trucks. I'm sure the radio doesn't work, and it was not claimed to be original with the truck or even installed in it when I got it.
Except for the panel, my 1-tons are all 5-window trucks and one of my trucks even has a sun roof!
