Are you referring to the fender that the licence plate bolts on to.
Mine were fiberglass with all the fittings that I sold with the kits.
The first few we're made from a plastic truck mud flap that I cut to shape to fit then used plastic rivets to fasten it to the bike with aluminum angle, bolted to the bike.
I can't imagine you ever selling anything that was less than well thought out, and not thoroughly tested by yourself. Having been around the community for a while, I feel confident that anything I would have bought from you would have been money well spent.
I'm referring to the cover that Yelvington sells to hide the center section of the trike conversion kit. It appears to be an injection molded piece of plastic that should be part of the basic kit, or an option, for, at most, $39.95.
P.S. (how old am I?) Is Yelvington trikes aware of this website? If not, why not? If so, why are they not responding?
