It's been several years since I swapped out my stock 2015 seats for the SLF seats w/Lime Green accents and I'm afraid I don't remember, but I see after checking the Seats parts pages for 2018 and 2019 that there are some changes, depending on the model years. Here's the Seats Parts page from Cheap Cycle Parts for the 2018 model year - https://www.cheapcycleparts.co…belt-mounting-all-options. I believe the needed bolts are #8, but I also seem to remember that there was at least one bolt on the passenger side, IIRC, that was different. Check the Seats parts page for your model year to be sure.
not concern with the bolts to the floor but the bolts that mount the frame rail to the bottom of the seat cushion as well as the sides
The screws that secure the seat bottom and back to the frames are Item # 9. Need 20.
