Distributor Advance

[ew1usnr]

I am looking for the mechanical and vacuum advance ranges for the distributors ...

After reading about the centrifugal and vacuum advances, I realized that I had never tested the vacuum advance canister on my distributor.

After dinner tonight, I slipped a two-foot long piece of tubing onto the nipple of the distributor vacuum advance and sucked on it. I could not pull any air through it and that indicates that it is working. Yay!

Happy Banana Dance:

If I did need to replace the vacuum advance on a 1963 260 V-8 with a Ford-O-Matic, which of these units would be the most correct replacement?

All three of the ones on the right with nipples are listed as being compatible with my 260. But, ... they reference some distributor numbers. Which number would be most likely to match my distributor?

Thanks, Dennis.
