Just gut home will look it up. That strange one actually could be it also with the electronic vac advance. 70, 71 and some 72.The ebay version sure doesn't even look close to original with electrical vacuum advance. Maybe some California abomination?
Pretty sure it is a dual point with one of those on it. Not cheap at all. Prob 7-800 for the core and 4-500 for the vac advance since it has a special arm also 440-6 specific. Went through this a year or so ago for a numbers guy around here.Just gut home will look it up. That strange one actually could be it also with the electronic vac advance. 70, 71 and some 72.
Your pretty much spot on only the six pack cars have I seen them on. Have them for the single point and elect distribs. Good catch single or elect in the picture. Prob a 72 book was just going to get a pic of the cover. Info on them is really spotty. Had a tread going about it a while age. And wait theres more some solenoids are innies and some outies also. I have them both on distribs. Stupid *** system really made for dieseling from what I see. But then again different opinions on that also. I go by the part number that belongs when I rebuild them, no one that I know of does Not the advances the retard distribs.. There are a few old restoration shops that can rebuild the regular ones. Usually a nice job on them also ($75-100 each)HalifaxHops,
All the information I've seen shows this vacuum advance/solenoid return mechanism on an ALUMINIUM single point distributor. The cast iron body distributors are either Prestolite or Mopar units whose vacuum advance mechanism attaches to the respective breaker plate differently and is secured with a small retaining clip. Also shown on your pix is the distributor cap's indexing locator tab. The cast iron body distributors use a different cap indexing tab plus cap hold down clips. I've not seen this device on cast iron body distributors. The aluminum body distributors have the breaker that pivots eccentricly rather than concentricly pivoting in the cast iron body distributors. Just my opinion of course.
