i'm torn in betwwen two types of sliders i want to do for my 60 so i wanted all of your opinions, i'm in between the ones that are mounted to the frame and the ones that replace the rocker panel(that you would cut out) but i want to know if the ones that go insied of the cut rocker panel are strong enough for rock banging? thanx in advance

weld to the frame, then you're good to go. think about the weight of a 60, then put a winch, beer, lift, beer, tires, beer, spares, beer and recovery gear... it adds up quick.
