I've got 2 Yamaha WaveRaiders and they have the time down holes (as I call them) on the back platforms. These pins drop into those holes to allow the strap to hole them down. One of these pins is broken. I'm wanting to replace both of these but I cannot for the life of me find them anywhere. I found one similar but it has the "ring" where the strap goes through. I was hoping to find the exact replacements. Does anyone know where I can buy these?
