Looking for Hall Plastic Wheels for Hang Glider

I'm looking for a pair of Hall plastic wheels. My control bar is getting eaten up by SB gravel... If you have a set you are no longer using or is buried in your garage somewhere, I would love to take them off of your hands. Feel free to give me a call at 805-451-5697 or email james.zender(at)verizon.net.
Cheers!
James
