Per title, rebuilding a friend's Wheeler Cross 3000 bike, and the driveside crankarm is buggered on it, so I figured I'd replace for him if I could find something cheap. I have a line on one out of town (Craigslist), but thought I would ask. 170mm arms, though longer probably not a problem. 28-38-48T rings, though the rings I have are fine. I believe it is a 110/74 BCD setup.

Not sure what Shimano replaced these with, so could go newer as well.
