A pair of aluminum spacers for the center cap on a Coy C-5 wheels. These are made from 6061 Aluminum. You can see the original thread
Herethat prompted me to help fellow board members with these. These spacer go behind the center caps to make clearence for the spindle nose. It requires using a longer screw (not included) New Price is $20 shipped for a pair.
