Try these guys but I've never used them before. http://www.mil-specproducts.com/Brands/Shell-Lubricants
That stuff is junk in any kind of hot climate/track conditions. There are far better options available. The red line is better but I've still come across diff-plate chatter after heavy use...
Isn't diff plate chatter a bit disconcerting? I called my local dealer and they said they use Agip on the 360. That looks easier to get.
If you use the NS it will chatter a lot. You can either use the regular or add friction modifier and the chatter will be gone.
