3B I came across a 1957 GMC 9700 today and was really hoping that it was a 1.5 ton that I could snag some rims off of that aren't grenades although from my research so far the 1957 GMC 9700 was a 1/2 ton ?? Once again things may be different for Canada. Also from the photos the front rims are a 6 bolt so not even close to the 1955 1600.

I could definitely see the front of my 55 sitting pretty with a 1957 grill and trim assembly.
