Default Re: Radiator overflow tank?

What "untouched originals" do we have to look at ? I haven't seen ANY nice original GMCs with AIR that were untouched. I spent a good part of my day looking through 1964 1965 1966 print dated GMC parts books and older books back to the mid 50s , no cans. The only radiator surge tanks I found were for BIG trucks. Zero applications for 1000 to 2500 series trucks and no listing at all to do with AIR. Without a picture of these parts matching these numbers I found, its impossible to say if they are the same ,but the books do not lie. If theres not a part number to application , theres no such "factory" part. The only theory that makes any sense is the can pictured of Steves was a service option made in the aftermarket or one of the BIG truck cans retrofitted to fix customer concerns. To say its factory without proof , or because you had a truck with one , or several , still does not mean it came off the assembly line this way. Every "original part" can be traced. So far , these cannot be.
