I have a 1954 Chevy Pick-Up which I want to lower in the rear 3". I bought an axle relocation kit from Chevy Duty to center a late model rear end in the center of the wheel well. I have stock rear springs and want to use lowering blocks. My problem is the aftermarket lowering blocks are wider than my springs and I will have to modify my lower shock mount plate. Does anyone know of a company that makes lowering blocks for these springs so I will not have to modify mine? Any suggestions will be greatly appreciated. Thanks Wayne
