Thanks for the heads-up on the Campy ring. It caused me to do more thinking and research, and I came up with an alternate plan. I found a 56t, 110BCD ring on ebay, and origin 8 cranks from the harris cyclery website. I hope I can use the 117mm bottom bracket that's on the bike. It may give me a fairly straight chainline. Anyway the 135 BCD ring didn't cost me much $18 with shipping. The 56t ring is cheaper still.
As you can tell, I am no bike mechanic, but I'm enjoying learning experience. Hopefully I'll have a nice bike when I'm finished.
