Congrats Jeremy, on the new wife and the arrival of the long awaited motors.
I sure could use some C washers for mine as well.
hillzofvalp, perhaps you could direct interested parties to your thread with your dropout problem, which has nothing to do with cromotors. The xlyte's tiny shoulders and small flats are a different problem. I really wonder if those dropouts are cromoly, they look too soft for that, perhaps you should consult a metal expert and make some measurements to see if they are the proper steel or something else altogether.
Back to my Cromotor, one of the last batch, I'm going to need washers on both sides, about 2.5mm thick, and "C" would be fine. I'm getting very close to putting this whole Greyborg together, so the "C" washers are going to be needed soon, though I'll do something temporary if needed. Take the time to get these right, don't rush them.
