i am having a good talk with myself. i was thinking sean, on slee's bumper the side supports bolt on the drivers side to one captured nut, and they say for added strength to through bolt and use the provided sleeves to prevent crushing the frame. if those sleeves are not welded into the frame...
when bolting to a boxed frame, like rocksliders for instance, how do i go about doing it? would i drill all the way through bolt sides of the box, and through bolt it? couldnt that squish frame? does a sleeve get inserted into the frame to stop it from collapsing, if so how? any help would be...
