Hello,

I am currently restoring all the dual point distributors for my cars and I see that some of them have this type of vac advance:

while some others have this type:

was that a year change or whats the deal? What is correct for each application/year????

Left 70 and later,right 69 back.Also,what you show are not dual point Prestolite,the Prestolite dual point does not use the advance with the locator tabs for the cap,the top advance you show is a 68 318 single point.

I will add to pay attention to stamped advance on arm, actual final bend length on arm at hole. So match what you have if these are original. Attached is picture. Notice two in center. The short extension at hole is DP. Longer extension at hole is the SP AL/Prestolite VC. Also save your springs and washers from the old, you will need them.

Also note that many early 70 distributors were built using the 69 style vacuum advance unit, I've seen quite a few original 70 Hemis and six packs this way.
