I am having a hard time identifying and finding the correct right side spark plug retainer holder. I have the left side (the one the the brake vacuum line runs through). I am looking for the one on the right (passenger) that holds the four wire retainer. It is near the vacuum advance on the distributor. If anyone has a picture of one, that would be awesome. I also need to know how it is bolted to the engine (intake manifold bolts or mounted to the intake). Thanks!
