kevindee here on HAN had a set for sale a while back, I don't know if he sold them.

I only know too well how hard sh wheels are to get. I had to replace one recently. Most of the quotes I got for a used one was $200 or better. Forget new! The dealer wanted $360 for one wheel! I watched ebay for a month to try and locate a single wheel, but there were none. Fortunately I found a local co. that had one.

The directional wheels are far more plentiful and cheaper than the sh. They are way more easier to get. ebay is no prob. for getting them.
