Forgive me if this is in the wrong section. I did a search, and that seems to be where other people mention registries.
I wasnt sure if any of you knew about this site since its been around for a while, but in case you didnt, you should check out
redmustangs.com. Its got production numbers, the registry (of course), a forum, as well as other fun stuff. There's even a place for mustangs with red interiors!
