Broken Fog lights- Vibe GT

[Maddawg46]

I set up a 2004 Vibe GT as a tow car behind my motorhome. I have very short mud guards. As it turns out the fog lights are in direct line with my fog lights. Just go back from a 2500 mile trip. At around 800 miles the right lens was cracked, then 1200 miles later the other lens broke. Chunks of glass are now missing. Going to get longer mud flaps.
Since the car is not made anymore, do you think Pontiac makes covers for the fog lamps? Or would it be cheaper to replace these with aftermarket lights and covers??
