The guys here have been buying #41 Chain at TSC.

When I looked it up on the Azusa site, they say a #415 was also #42.

If you can't take your sprocket to physically check it, I'd go with the #41.

TOMORROW, I am taking my sprocket to the TSC and checking the #42 they have there as well as the #41....I will post a full report tomorrow evening.
