FWIW, I got an email this am from Larrys Thunderbird. There's a number of parts on sale, including the Tbird valve covers, for $145, down from $198, each. I don't know the quality of these parts, and I know there was a recent problem with a soft top, but my dealings with them recently on the windows and channels was fine. Pricing right with the other guys. I'm on the west coast, so shipping works in my favor with them.
