75 gmc production numbers

[ope]

Hi anyone know of where to look to see how many 75 GMC's were built with a breakdown of models? Also.. where I could find info on what looks like a factory AM/FM 8 track? a pic even? Also appears to have a camper tie down set up with shocks that bolt to the cab?  thanks.

Thousands, and you won't find breakdowns buy models as there was only 1 model of each series; C10, C20, C30, K10, K20, etc, etc..

Finding the breakdown by the trim level is even more impossible.  Myself and others have tried to optain this, but unless it was some rare truck like a Gentleman Jim, you can consider it very UN Rare.

The camper setup with shocks are part of the Elimi-pitch option.
