I just installed body bushings. I started out with using the regular rubber reproduction bushings and I thought that was going to be just fine. However, After everything was torqued properly, I had float in the rubber bushings and it seems all the compression was on one side. I ended up popping the compressed bushing side completely off the mount when the body moved and came off of my lift when I was installing a coil spring. It was at that point I decided to go with Detroit Speed's solid (coated) aluminum body bushings. It was the right decision. Now it's mounted and frame is solid to the body. It could be the reproduction mounts that I used, but something was not right about it, so I fixed it with solid mounts.
