I bought a set of the rock sliders used and have no idea how to mount them. The back mounts into the frame but the front looks like it might bolt right up to the plastic floor and that doesn't look right to me. Does anyone have a set of instructions/parts list for the 2877389 aluminum rock sliders they can copy and send me? Ok I went to the dealer and he was nice enough to copy me the instructions. The bolts are easy enough to find but the two brackets to mount them are missing and I'll have to com up with something. Maybe some 1/4 aluminum angle? Not sure what size I need, does anyone have any suggestions?
