I had him weld the fender too, if I really need to remove the fender, I have an angle-grinder. Yes he did weld up the area behind that, and I will be using them as air tanks. As far as my old rockers go, I did not save them, it never crossed my mind.
Anyway, I got them painted before the rain. (If only I had a bigger garage)
I'm so happy with how they turned out. I can't wait to try them out. Plus now I can put a high-lift anywhere on my Jeep.
