Thank you, now I understand the vaccum set up, and I was correct but without my air cleaner installed. It will be soon, but for now I'm using an aftermarket unit.

The vaccum advance for the distributor on my car is located on the left (drivers side of the dist. The hose has to run along the right side, and then bend bhind the dist connecting the the advance nipple which faces left (drivers side) which I thought was odd.

I have checked the boosters the local parts stores can get but none of them have the cad plated boosters. Also, everyone seems to have diff sizes which is why I was looking for the correct size. I will try looking at som of the web pages selling resto parts to see what they have to offer. Thanks and god day friends. Mike in Oregon
