That went about as well as expected. Marc has the glass and offered to build a crate and ship it to Seattle. I can't believe it.
One funny thing for people to acknowledge if you're seeing this in the future, be careful when doing your research. I found a brand new window in Florida this morning, but decided to shop around and get quotes. When I found that to be the cheapest option, I called back and it was sold. The glass shop told me that it was probably another one of the parts suppliers I contacted, buying it because they know it's hard to find and so they can crank up the price. The 1st glass shop would have charged me $325, but the dealer who probably bought it quoted me $500+.
Regardless, I'm happy to have found Marc. Thanks a zillion!
