Here is some pic's of the Corbin after market backrest.
Construction seems pretty good. This is large one at 12 x 10. A smaller version is available at 7 x 7.
Think I might send back to trade for the small rest. Don't know if larger one is just "to big"
On my gunfighter and lady seat the bar does not come through all the way allowing me to secure it with supplied bolt. Don't think that will be a problem since will only use when wife is riding with me. Also will avoid having to remove the seat to remove backrest each time.
back is adjustable by loosening the set screw seen on the back.
