At one point I had 5 of these.I got lucky and sold one for 40 dollars and another for 30. The last three sat in a corner of the garage for over a decade . At one point I thought about using them as skylites in my cabin . I'd put them up on craigslist and elsewhere with no luck.Then one day I found a kid with a 65 valiant and he was thinking about getting a Barracuda .He gave me 50 for the three and I was glad to be rid of them ! Thing is,they rarely break and people think they are the most valuable piece of glass on the planet but in reality you can't give these away .
