One-piece seat screw or two-piece mounting nuts
Gloss-black quick-release kit 10500093 uses a hand-operated knob and nylon washer for the specified one-piece seats with SAE ¼–20 hardware. It excludes spring-loaded rear seat brackets. Mounting nuts 10400049 instead come as a pair for the listed two-piece seats using knurled mounting nuts. Match the fastening arrangement before choosing the black finish; the pair of nuts does not convert a seat to the quick-release screw system.
