the Frankentruck is actually a combination of about 8 diffrent trucks, 56 US cab that had been reworked a couple times, with mostly 57 GMC sheet metal on a 58 CDN frame, with 56 - 58 driveline and a 60's bed, I was "saving history" from the scrap heap [and cleaning up the yard!] ... the pics there are most of what I have of that truck and I no longer have it, but there may be some of use on the "details" link below
