I would also suggest a quality fire extinguisher. Halon or Halotron. These are rarely on sale but just so happens than ZoroTools is doing their cyber monday sale which can save you 20% - 30% today only.
yes the list goes on and on, just placed two large orders with Gordon's. I plan on making a steering brace, I have seat belts, still not sure who sells the Pertronix.
what size radial tires are you running? where do you get them?
I'm running, for the past 7 years, DiamondBack Classic radials
185/80/13/11/100 185/80R13 - 2.25" Whitewall Tire $144.00 back in 2008
Slightly thinner whitewall (2.25") than original, but look fine - maybe other vendors have wider ones now, but back in 2008, this is what I settled on. They have worked great, but I don't put more than 300-500 miles a year on them. I second having your wheels media blasted and powder coated, before you mount new tires.
