So I have a vacuum leak and found it to be the advance on the distributor. So now in my searches I have found some who say the car and truck units are different. I believe that my motor was originally from an early 60's car but don't know how to tell for sure. I really don't care if it is the correct looking unit I just want it to work properly. I'm just hoping you guys can educate me on stovebolt vac advances before I go out and order something tomorrow and have it be wrong.
Thanks, Chuck
