No experience, but look them up online if you have no luck here. There is one here in Detroit I know of.
http://www.thehubofdetroit.org/ I went there. They appeared to not turn down too many old bikes and it was too overstocked for my preference--lots and lots of old bikes and common parts but they may be able to offer some insight. I may try checking them out again but it's not just a hop, skip and a jump from where I live so that is one impediment.
