A Mechanic Building my version of a 454SS silverado using a 91 c1500 silverado edition. So far all problems underneath my truck have been fixed. This includes axle bearings, pitman arm, muffler replace with super 40's, and light package all the way around, and a roll pan. Next are tires and rims and bilstine shocks. I have the rims but no tires or shocks.
