I was supprised with the gas and brake lines. I pulled them off before removing the frame and after I was done it took just a little tweaking of the lines to line up to their origional spots.
As for the law, It takes some explaning what I have done for someone to see it. It looks stock and if I posted pictures know with the paint scratched and dirt/mud on the frame most wouldn't spot it. Also most people I know with 35's or better (mostly Jeeps) would never pass 1/2 the laws out there.
Second, as I said earlyer, you can't weld on most frames. Most are made with a harden frame and if you weld on it, it will break at the weld. That's why all the aftermarket parts like running boards and such are bolt-ons and not welded.
