Hi Stooz...
If you are looking for more info for your trucks try ebay. I've seen truck service manuals, data books, advertising materials, etc., both reproductions and original, offered on ebay. Much of the material I've acquired came from there.
Couple of other questions, does the truck have an engine operated air compressor? Also is the two speed axle vacuum or electric operated? The interior pic looks like an electric switch on the transmission shifter.
Again you have two rare and great lookin' trucks!
