So I just bought a 750K3 and it's pretty much road ready and just needs a few things here and there. On of the projects I'm working is putting the seat on. The pan had nothing on it... No hinges, latch, rubber... I found some hinges on line and when the arrived today the do not line up with the bike and the seat. It's not the hinges that are the problem but the seat itself. As far as I can tell the holes in the seat pan do not line up with where the hinges should be... Do I have a wrong seat? How do I tell? The seat is in really good condition, so I would like to use it one way or another... Any ideas on how to get this thing mounted??? Thanks for the help!
