Update, I looked again on the frame rails with no luck. The engine stamping is under the exhaust manifold so until I pull the front end and or motor it is still an umknown. I bought the truck and have it at the truck farm now. Interesting story, it had supposedly been restored was in a building that burned down around it an several other vehicles. I bought it from a later owner. No title, no ID plate. Clearly a 58/59 GMC based on the dash and front clip. Portions of the "cameo" bed were still there, including one damaged fiberglass outer fender. That fender clearly had 2 stainless steel stips down the side. Maybe it was a '57-'58 cameo bed, no way to tell. Tracking down the seriel number will help I hope. ANy more thoughts are appreciated.
