I recently had a foglight crack while driving. All 3 of the bolts that mounted the foglight snapped/broke off when I tried to remove them. The foglight mounting bracket was so rusty it fell into pieces when I pried on it from under the car.

I have a new bracket and foglight ready to install along with the required mounting screws.

My question is whether or not I need the spacer/s shown in the foglight assembly diagram from the general Subaru parts guide? The part# is 84937FA000. I cannot tell if these spacers are required for my install or not? My local parts counter guy was no help.

Thanks!
