1956 GMC Napco 4x4
 

Here's an interesting truck: 1956 GMC 250 big rear window cab, Pontiac engine, Hydramatic, Napco 4x4 conversion, dual rear wheels, along with a number of other unusual options. https://www.youtube.com/watch?v=vI0ZLzggotk It's a project, but could be a pretty cool truck when done.

Man, Would love to have that truck. Sad he has to let it go.. Will re-post for him.
