I got my parking brake in a box when I bought my car from its previous owner. He said it never worked properly and when he went to the wilwoods he never put it back on. I know Wilwood offers a parking brake rotor kit that goes in the drum of the rotors, but I think its a special package you have to buy.

I thought I was going to freak out without a parking brake, but have learned to live without it. It would be more frustrating to have one on it that didn't work. My understanding is that on the early cars, lots of people removed it.
