·The new part catalogs are very confusing with respect to the dual vac advance. I have a 68 with a 289 which is supposed to have a dual advance set-up. I tried 3 different suppliers and, each time, received a single advance unit - even one vendor's Ford part cross-reference was wrong and I got a single unit again. I finally gave up and ordered a used dual set-up off e-bay.
That being said, my recollection from this was that 302's used the single and 289's used the dual. It is spelled out in the distributor vacuum hose connection diagram in the Yellow/green Ford repair manual (I can't remember the vendor but can check tonight if you still need it). There is also some trouble shooting info in there that tells how to diagnose the dual diaphram units.
I used an Accel distributor on another car (non-ford, <gasp>) and had such terrible luck I swore I'd never use an Accel part again. Their tech line was even worse. My problems went away when I pulled the Accel distributor out. Can't speak for the Ford application, though.
