Get the weld in kit too. It is worth it. Just be a little patient when installing it.
Tim, you the only person I have heard advise against this mod, and probably could have easily benifited from it. Perhaps if you had done it before you ripped the whole box thru the frame the kit would have fit better. I am sure that kind of stress will make even the best product fit like crap.
I say run both kits, use lock nuts on the outside, check the bolts often and have fewer worries while out having fun /forums/images/graemlins/waytogo.gif The whole point is to get out on the trails (tread lightly) and enjoy your rig.
