I still couldn't find the guy that put the bike together but I'm not givin' up! (Now I'm on a mission!).
Here's what I could get out of a random parts guy: It's an 80 spoke, 19 x 3; (I couldn't verify width but it did have the stock Dunlop on it). They can get a matching rear and they want $999 for each, (a little pricey for the front, IMHO). He was a little tight lipped about who they got it from, but did say it was put together locally. That's about all this guy knew and I had to get back to work.
I'll have to do some more digging over the next week or two; New Years' weekend there is a custom car and bike show here and I hear a lot of the custom builders in town will be there. If not, some of them hang out at a local refreshment provider (Billet Bar in Scottsdale) so I should be able to find out something.
