This is a pair of carbon weight brackets (front/rear) for the brass left side weight on the Chief-12.2 1/12 oval pan car kit. Brackets are 4-40 tapped to omit the use of a lock nut.

NOTE - This is a different product than the original Chief-12.2 left side weight brackets (#13390). The rear bracket is slightly longer on the 12.2, please purchase the brackets relevant to your version of kit.
