I'm all new to the Harley world so this is the problem.
Bought a 2009 Dyna super glide custom had it changed to forward controls. Now this is the problem . after looking throw the 2009 accessories book i changed the seat to a sundowner deep bucket seat witch i like so i ordered i back rest for the miss but the sissy bar sideplate
they gave me wont work because the seat passenger width is wider the back rest needs to move back a inch or two to clear.in the book it dose not give sizes. the dealer has not got back to me yet .

 

Something is not right then. They should both fit just fine.
Lots of people using the Sundowner seat with the Harley sissy bar.

 

Thanks i think they gave me the wrong sissy bar side plates wish they would get back to me. ill update when i hear

 

The sundowner seat is a tight fit with sissy bar side plates. Are yours rigid side plates or are they quick release? i have quick release sissy bar and my seat touchs the bars if you have rigid its going to touch and be tight.

 

I have the sundowner with the quick release sissy bar hardware. It is tight but not as bad as you are saying.

 

Thanks your picture is what I'm trying to do.the ones i have are quick release is there different lengths sideplates??

 

I went with the pillow seat on my fatbob. The pillow seat is tight at 10"s wide in the rear. I believe the sundowner is 12"s in the rear.

 

thanks just went to the garage to try it again it will work. touches hard pushes it in half to tree quarter inches just cant believe Harley would make something that tight

 

you're going to find a lot of sh_t you can't believe that HD does. I did,..but It's MY Harley so I'm happy.

 

The Sundowner is a very comfortable seat, and the ladies love the back seat with a sissy bar!
