What exactly falls under "factory store?" There's an Oakley Vault near me. I'm in the Phoenix AZ area if that helps
I would say if you were close to an actual Oakley Store, then perhaps they could provide a solution in store or get the parts needed. A Vault store I am unsure of their capabilities.
I live in SoCal and two of their stores here have onsite optician. My girl works at one of them and they were the ones who got me the multiple Badman nose pieces. If you can't find an acceptable solution, you could drive to Scottsdale where they have an optician onsite as well.
