My dist. is held on by a simple clamp. The 4 vendors I checked do not sell the complete distributor clamp with vacuum advance, only the vacuum advance.

Any ideas who has new, complete vacuum advance dist clamps?

What is wrong with yours?
There are three different styles, can you post a pic of the vacuum advance you have?

Currently I don't have any working vacuum advance linkages. The one that was on the dist in the 'box of parts' is not for the 235 dist (the clamp is to large.. does not grab the dist I have for the 235).

The motor is a 58 235 with a rebuilt dist from Advance auto. The dist clamp I am using was also in the box-o-parts. It fits the rebuilt dist but has nothing to hook an vacuum advance to.. its just got the clamp, a clamp screw, and a flange for the block hold down bolt.

I would prefer new, but I will post a wanted ad if I cannot find a new one.

Is this what you need in combination with the part/collar/clamp shown at the links above?

'54 3600 has it right..

The vendors sell the vacuum advance linkage, but not the distributor clamp that actually clamps to the distributor.

Had the A R gauge stamped on it also

I went with the $70 Advance Auto dist because I though the vacuum linkage in the 'box of parts' was the correct one.

I'll run without it if I can't get one... just would rather have a bit more MPG out of the old beast. A G506 clocks in at about 8,000lbs empty... that's a lot to ask of a 130hp
