Here is an item of interest; a barely used joystick mounting bracket for GC joystick controllers. This mounting stick is almost perfect, just a minor little scrape on one side that won't be noticed.
These can be found mounted on many Jazzy and Jet power chairs by Pride Mobility. Please check the Compatibility tab carefully for a full listing of compatible models. Most Jazzy models changed joystick remote connectors during their production runs.
