Yes I do know what I am talking about! I saw the truck setting there for sale for $900.00, and looked at it. The side badges and glove box door said C-30 on the truck and the rear end Was a 1 Ton Dually rear, with Duals Not a full floating rear. But it had Trailing arms and Coil Springs with the optional helper leaves on the Trailing arms, And it also had the 1 ton front spindles. But I didn't think that they made a 1 Ton like that with the coil springs! So that is why I was Asking Thanks.
