ive had these poison spyder rock sliders sittin on my back porch for a few months now. has anyone installed these? i know there not that hard but its just a huge pain in the ass. How long did it take? any tips or hints before i finally do this install. These are the rock sliders with the rail, and they mount between the body and my body lift mounts. so i know i have to shave those down 3/16 of an inch.
