Rovertech,
I came across this site recently
Dezo's Garage that has a bunch of publications of interest to Stovebolter's. The site says "All brochures have been put into PDF format for convenient downloading." so apparently accessible to all that wish to see and download them.
There is a large listing of various brochures posted for both Chevrolet and GMC trucks, although not all years area available.
The primary one you may have an interest in is
Task Force 59 Chevrolet / models and specificationsJust one of many resources out there to help us out.
