I have a 67 Camaro with a 6 CYL 230. I have just rebuilt the motor and want to replace the vacuum spark advance. The AIM 6- C3 shows a "Pipe Assembly, Spark Control" Does anyone know where I can get one?

The one that I have runs into a T with a brass color pipe coming from the transmission. The third part of the T feeds into a short rubber hose which is attached to the carburetor. I am certain that this is a Bubba fix as were most of the things I found.:clonk:

Thanks, Joe
