So I've searched high and low on this forum but still couldn't find the answer to my question. I am installing new shocks on my 2003 AC 4WD and decided to go with 5100's, new factory springs and top plate. The shocks came with two washers and two bushings each. The top plate has the bottom bushings built into it. Are you guys replacing the bottom bushing or reusing the factory? Mine are already assembled and ready to put on using the new factory top plate and bottom bushing. Do you think this OK or do I need to take these apart to install the bilstein bottom bushing. I know the Bilstein 5100 topic has been beaten to death but I couldn't find an answer with the search tool.
