I see no one has yet answered your question about the dock spacer, so if you're still interested here is the solution I use.
Download "LeopardDocks" (free app), and from the same website grab the dock called "Mountain Lion"
Run the Application and install the dock.
Thanks man! Found it! Gonna install it later
