Air conditioner fan grill cover?

[nmaiers]

So whilst camping this weekend, a fairly large eucalyptus branch was dropped onto my '05 TM 2619 by a couple of crows at 6AM. No joke. I don't know how they did it, but it fell directly into my Coleman rooftop air conditioner. I couldn't recreate the event if I tried, but good thing I didn't turn on the unit as the branch was positioned down into the unit and the fan blades would have been toast.

Good news- fan blades are intact. Bad news, the black plastic grill cover/grate is broken. It looks like it's part # 9233B3151 but I've tried several places and it's discontinued according to the folks at RVUpgrades.com. Anyone have one laying around? I think the only other alternative is to buy a whole new shroud.
