Can you be more specific, like where these bolts are? A pic would help a lot too.
The only OEM floorboards on a 1200A would be the passenger foot rests. Is that what you are referring to?
Have you looked on a fiche to see what's listed?
If that is a pic of his bike, in his avatar, then those are not OEM floorboards. Are you talking about the big bolts that hold the floorboard to the frame? Also I'm not sure what you are asking when you say change to from 10x25 and 10x45?
