Installing C-Rok Help Its Dark

I am finishing up installing my crok plate and I have a stock bumper right now. I would like to keep this bumper for a while because I just like it. And I need to know if I can leave the clip nuts (nuts the clip onto the bumper bracket) on or if I should take them off. If I leave them on will it make any problems? Or should I remove them and just use some standard bolts behind the bumper bracket? I hope someone knows what I am talking about

Thanks

Either way should work fine.

These are the frontmost two bumper mount bolts right?

You can leave them on...... or take them off and use a regular nut.

I just left them on. No problem maaaan.

if you have extra bolts/nuts laying around, i would go ahead and switch them to the bolts/nuts. i reinstalled my factory bumper this week after removing my arb bullbar. in the process 4 of the little clips snapped in half. i could still tighten down the bolts, but it would have been much easier with a bolt/nut combo.
