Well, I just installed an 89 bumper on my 87, no fogs in it yet, I have to get a set, but I was wondering if its a bad Idea to put the undercover on while the fogs are out? Would this create a massive pocket of air that would rip out the under cover or should I not worry about it? Or should I head to autozone and grab some cheap fogs for the time being to remove the fog holes that are there now?
