I'm looking for a grill for a Freighliner FS65. Freightliner's grill wasn't built to tough as it seems like just about every one still on the road has a cracked or busted grill.
Good luck with that, as you just said they are built pretty cheap. I ended up buying a new one. Even though I have a pretty old fleet I try to keep them looking decent.
Check Ebay, I've never bought a replacement FS-65 grille (if we have a damaged one we swap it out with a trade in and keep the good one) but I've picked up a few "knock-off" C2 chrome grilles for much less than the dealer charges.
