Have a Zipp 404 firecrest and my preferred hub for this build. Been trying to familiarize myself with any nuances of building a Zipp wheel (this is a front). Anyways, I know they need washers.
When looking online, some washers listing say they are for a specific model of rim. I'm wondering if anybody knows if I just need a Firecrest washwer or a Firecrest 404 washer.
Some ebay listings I've seen say 202 or 303. But some don't and simply say Firecrest.

Any help is appreciated.
