Sharkey,
Thanks for getting with Joker on this. I actually considered flipping the expander, but then the bolt was too short. I grabbed a longer bolt today after seeing your post and gave it a shot. It looks like it will work ok, however now it is so hard to turn the bolt the entire assembly wants to turn. The body should have reliefs cut to facilitate a wrench like this picture from Joker.

I don't really want to just grab the end with pliers, as it will mess up the aluminum body pretty bad.
Seems like it would just be easier to purchase the black replacement bars for the bike..........if someone confirms the ID for me I will just go that way.
