The Enchanted Voyagers Association is a chapter of the American Voyager Association. The club was formed by Kawasaki Voyager Riders in New Mexico, but is open to all riders. Please feel free to use this service.

You might also do a cearch on the forum as there are several different posts on armrests. Chris near Kansas City I believe has made some, but don't know if he has any left.
Good luck
