Cruisin' on my Bluebird
I believe the "trim washers" Found at your local hardware could be similar solution to the spoke washers I received with my CB Italia wood rims. To be sure, take a nipple and know your wheel's spoke hole diameter when you go to the store. I usually carry a caliper with me when I do silly things like this. CB prescribes doubling the washers for installation and supplies double the amount with the nipples.
