Ok, I traded my '15 Freewheeler for a 2019 and like any rider I stripped the old bike to put on the new. The chrome reciever plate for passenger backrest uses different button head screws. I checked the catalog and it says the same on all Freewheelers (1/4-20x1"). My bike needs 12-24x1" WTF. That is about as common as a skinny harley guy. I had to go on line and find some stainless steel button heads that would work. Maybe I got a custom Freewheeler.
