Mike had a backglass for my City Slicker I wanted on ebay and instead of trying to buy it through ebay I just called him. I ended up asking him if he had any other parts for it and he had the bottom cab with everything in it. He held it for me for a couple of weeks till Expo. There's a thread with his phone number. Here's a link...

If you still want it, don't be afraid to buy it. Deals fall through all the time and may have been what happened for him. It's better to deal with him directly if you want something. To me, Ebay's just an advertisement for his business. Call him. He may have more parts that you will want.
