I'm thinking about making my own sliders and I'm wondering what wall thickness most or the commercially made ones are? I plan to use 1.5x2.5 or 3", or 2x2" for the main tube and mounts. About the installation, I've heard some people weld them right to the side of the frame, which seems easiest, but kinda odd, I'm use to bolting things to a frame. Do some companies/people bolt them? I'm plenty capable of fabricating, just new to Cruisers...I'm use to 1 ton pickups with big blocks and 44's.
