I'm building a 57 1/2 ton shortbed stepside with 78 camaro front clip and 81 Z28 10 bolt with rear disc. The truck is completely dissasembled, so kind of hard to take measurements. Does anyone know what the widest tire/wheel set I can put under stock fenders are and what the wheel offset needs to be. I'm sure many have used similar setups, I'd love to here what you're running under your rigs. Thanks, Matt
