Fog hollow is a bike place in my neck of the woods. Here is there website http://www.foghollow.com/index2.htm
Call them they might be able to help you.

 

I have them on a couple of my other bikes including the harley.Storz also makes a real nice damper but it is alot more money.I'm out of town right now when I get home I will look for the mounting directions.

 

I have been waiting for two days to hear back from them. I know that I didn't purchase the item from them so its understandable. I was hoping to buy this one and save a couple of bucks in the process. But it might be better to buy new in case of problems.
