George,

I have seen very few that aren't cracked! I have 2 that have been repaired, and one needs it again. A year or so ago I priced a new replacement, at around US$325-$350! I checked salvage yards, and specified undamaged. Some laughed at me (politely). I keep hoping someone would STC a fiberglass replacement, but I've not found any yet.

Anybody want to start a cottage industry?
