Has anyone tried to put on Wheel Simulators on a 3500? I bought a set from wheelsimulators.com on Ebay. The fronts went on very well. See picture below. I come to find out the rear outside studs are not long enough. I need a good 3/4 inch more. Has anyone else had this problem with attaching the simulators, and if you found longer studs, where did you buy them. Also on the subject have any of you experienced using valve extensions? So far online, most people have had bad luck with them.
