Harley Davidson Seat bolt retainer.. Picture is spacers fitted to a Breakout Harley Davidson parts. You are buying two plastic spacers These spacers are a direct replacement for the cheap horrible Harley ones, Instead of the annoying standard ones that slip when seat is off, my replacements are threaded so they stay put, easier to put seat on and off Spacers cannot be seen when seat is fitted. They are a great upgrade to the awful cheap spacers they fit in factory.
