Looking for a passengerbackrest and sissy bar for an 05 electraglide standard. The bike has a two piece mustang seat on it. The Harley book says that their backrest wont work with aftermarket seats. Any suggestions? Thanks Rick.

 

Would't the Mustang one work?

 

Opps, I re-read your post and think that I missed the point so let me try again.
If you are looking for a passenger backrest the Harley one will work, I have the medium height and it works great with my two piece mustang. I think the backrest you were talking about might have been the driver backrest, which will not work with your mustang seat or any other aftermarket seat.
