Steve - The only discernable difference in appearance is the number on the nose is smaller. I'm hoping some of the folks in attendance yesterday will post some photos of it in action on the Electrathon page. If they do, I'll pirate a pic or two and repost them here.

Tech - That's an excellent idea I hadn't thought of. The local ACE Hardware has them in many different sizes. I look right at them when I'm getting hitch clips for the spindle nuts and it never occurred to me to use them for this. DUH! Thanks for the suggestion!
