Curious issue

[CarterD2015]

My buddy went to Decatur swap meet this weekend and brought home what he says is a numbers matching 71 c10 long bed with a 350. The curious thing to me is that it is a leaf spring truck. I was under the impression that all half ton two wheel drive Chevys were trail arm and that gmc, and 4wd were leaf. I didn’t ask him to send me a pic of the inside of the glovebox door. He is happy with the truck and I’m happy for him. I was just curious if Chevy made a 1/2 ton leaf spring truck.
