So I'm going to put my '52 COE on an '82 GMC C3500 dually chassis. I'm planning on drop spindles, PROBABLY air ride, and PROBABLY a 4 link rear end. My question is what size tires do you folks usually use when you do that? What do you use for control arms? For a frequently driven tow vehicle, what do you have the ride height set at? Thanks for your help?
