Description Reviews Sparco Universal Aluminum Seat Brackets. Like new. Installed for fitment, then the plan changed. One set of brackets are new and never installed; one set was installed but never driven or raced (mock up bolt in). Perfectly good and 100% safe. Selling for less than new! Ask any questions. Fits most Sparco seats. Part number 600W. Sold as one set of 4 that will do both front seats.
