I checked Pinwalls store on ebay and they don't have any listed. Thats where I got mine from too. They may be out. You may need to call them. 330-879-9910 I bought mine last month from them for $33 shipped. In fact I dont see any listed on ebay at all.
These look like they would work, with the angle and all. But I'm not sure of the handlebar diameter.
I just checked and you're right, I didn't see any listed at the moment
Somebody here posted some inexpensive chrome pullback risers that would accomplish the same thing and I think they looked better and were cheaper
If you are set on the ventures (I have them and they look great buffed out) then just wait for some to pop up on Ebay. You can still mount your fairing, you will just use the more forward and higher mounting position. When you get the risers just move the fairing back and down.
