Have seen multiple threads talking about how you can add the new rmz 250/450 fenders and plates with only a little bit of drilling. Can anyone give me some in-depth information on this? What size drill bolt do you use? Also, can you convert a rear fender without messing with the subframe? All I'm planning at the moment is the number plate and front fender. I might just get a regular rm fender and see if a rmz number plate will fit?
