Someone backed into me breaking one of my fog bezels. I found a cheap set at Pep Boys that were similar. Turns out they were the exact size so I simply swapped the bezel rather than the entire lamp. BTW, they cost me like $25 and I have still have a spare bezel, 2 bulbs, brackets, etc.
So take a few measurements and head on down to your local Walmart, Target, PepBoys, or AZ or...... You might get lucky.
