It will run but will be sluggish without it. They are available at most of the aftermarket suppliers. Many are listed on this site. fred

If it won't fit on the older clamp just use the whole assembly. It slips right off if the clamp screw is loose.

I specifically asked if the vacuum advance was good and it was. Although the plating is not very shiny  Plus now I have a second dist rebuilt as a spare. | | |
