I have a frozen valve that I need replaced. It is off of my 70 chevelle and after reading some information on various groups I was wondering if I can use a newer valve from 71 and up years. If I can adapt a new vale do I have to remove or change anything on the existing brake lines. I noticed another valve block on the lower frame that has a wire that connects to it for the brake light to activate. Can I leave this on the car? Right now I have no rear brakes on my car.

Thanks

Here is a site that has the original valve. It is called a Hold Off Valve.
