I have a brand new, never mounted, right front assy. It was bought back in the late 2000's for a spare. It does have some slight rust and tarnish from sitting in my shop. I've been using it to balance tires. I"ll take 50.00 for it, plus shipping if interested. SKS went out of business around 2010ish.
You have an early 2000 model, I think. I found an old phone number(912) 772-3876 (Studier Kart Supply) in Guyton, Ga. I'm not sure if it is still in service. They have a honey producing business that also shows the same number. Ask for Joseph Studier.
