I just bought a black cap for it, but when I took this one off, it was never used. Brand new brass terminal cap and rotor. I can put up with a blue cap for a little while. If it really bugs me later, I'll paint the cap.
I got new rear springs and shocks for it too. They haven't made it on the car yet, though. As soon as my DD sells, I'll order the wire harness and brake stuff I need.
