I'm in email contact w/ Vicki at downs about once a week, and once it gets closer to my build, I'll probably be going down there at least once a week. If you've got any questions let me know.
They've got a pretty inclusive catalog, and they also have a DVD about their operation. If you need contact info, let me know.
I've been in their factory and seen bodies in all states of assembly and have been very impressed.
I also closely inspected another 3W that was ready for delivery and the fit and finish was as good as any I've seen, other than block sanding I'd say it was ready for paint.
