I had a friend of mine build me some rock rails for my ZJ. The only part in the design I was unsure of was just exactly how to mount them to the unibody. I tried drilling, tapping, and screwing them in but after one hole I decided that wasn't the best idea. Any suggestions? I would prefer to have them welded, could I have them welded to the unibody? Here's some pics to give you a better idea.
