Well i was purchased as a complete truck. I bought it mainly for the cab but being bought sight unseen i didnt know that chassis had been done. I had only seen pictures of the cab. When it was shipped the owner pieced the truck roughly back together to my suprise. I'm not sure on all the specifications for the 3600 in regards of wheelbase etc. Two years ago i bought a shortbox 3100 well its a 1300 canadian built truck. The cab is to far gone and the chassis was rusted out in one spot that had moss growin on it. This is the reason for making one truck out of two on the 3/4 ton chassis.
