10mm or 15mm hubcentric spacers
 

Any spacers will do, used or new. I'd be willing to buy it for around $50~$60.
Local preferred, 90020.

Also, what does "feeler" mean?

I have a set of brand new z1 stud replacements type. Their 10mm spacers. Picked up for 50$

Feeler is like "interest" just to see who would want that part
