The Stovebolt Site Forums The Shop Area General Truck Talk 1957 Chevrolet 3/4 - was my truck a Dually?

Trying to figure out if my truck was/is a dually?

I have a 1957 Chevrolet 3/4 ton and the rear end has the h052 4.56 locker and 13 leaf springs on each side. 8 big ones and and 5 additional smaller ones on top stacked together.

I am trying to figure out if it is or was a dually and where I can find split dually rims and what size 17.5 or 19.5 my truck GVW is 6900 also that's the strongest for the 3604 series.

Thanks for any help!
