Depending on your pickiness, I have a set of 126mm spaced wheels. They are Shimano 600 tricolor hubs with a 7-sp freehub and UG casette.
The wheels are mismatched, Mavic MA-40 rear and Araya CTL-370 front. The wheels themselves look pretty close, but the sticker mismatch is a dead give away.
If you need shifters for 7-sp indexed, I have the set of 600 tricolor that came with it. I even have the rest of the group if you are wanting to just upgrade the bike to 600.
