I am in the process of rebuilding the motor on my '66 GT Convertible and I just had the distributor rebuilt. When I got it back the vacuum advance had been changed to the type for a rubber hose and not the threaded solid tube type. The original one is bad. I have searched in numerous catalogs, auto parts stores, etc... and I cannot find one of the original threaded types. Does anyone know where I can find one of the original ones or what other alternatives are available? Thanks in advance for this great for and all of your help!

As long as we are on the subject, where would the vacuum hose run to? On my '68 coupe I have the fitting but no hose connected to it. Thanks in advance for any replies.

Vacuum hose goes to a port on the carb, where the vacuum is created at the venturi's and not in the manifold. The former is called Ported; the latter is unported. The latter has vacuum at all times; the former only has vacuum when you're sucking in more gas than at idle.

thanks! I have one on the front of the dist advance (looks like a big nut) that goes where you say. I also have a nipple on the top of the dist advance... any idea where that one is suppose to connect?
