Need help on parts for the 2006 season.

[SlowWhite]

I was told by Track officials that as of january 1st i would no longer be able to race unless I installed a Sealed Coolant overflow tank along with a 20lb radiator cap?

Of coarse I'm looking for something Shiny, but other then that I don't know much about what to get, look for, or where to get them at?

Also what's the exact code on this engine diaper BS? do I need to get one as well? and if so how do you install one? and where do you get one for our cars?

I still have a 1/2 tank of race gas and I want to head back up there there next event is on the 4th.
