So I am still struggling with a few distributor questions. I have been doing my research and am at info overload. The most helpful thing I found was in the tech links where JimC and Zepp were discussing Distributors thru the years.

So I figure the reading is basicaly right to left on the photo - the early dizzy on the right, 69-74 with vac retard (The vacuum module is on the opposite side from the rest), then things get confusing for me. The next two have Vac advance, the last one looks like it has no vacuum module (88-92 maybe?) and then there is the electronic dizzy at the top (I am guessing '78) and finally something with a two stage vacuum on the top right.
So, with this limited knowledge, I checked what I have. I have two worn out F motors on the shop floor with the same dizzy and a 2F I have just put in the truck. I pulled the distributors and clicked this pic:
The one on the left appears to be a vacuum advance from late '76 & 77 (the motor after all was 11/77 but that means nothing) and has a label on it that I can make out "2F" on the bottom. The other one appears to be someplace between 69 and 76 , extra small with vacuum retard.
My plan was to throw a Pertronix in and a Flamethrower because I did not want to buy another dizzy and I like no points = no screwing around with dwell. Plus the one on the right worked fine in the worn out F motor before I took it out but the one on the left is specifically for a 2F. (both are Teq dizzies BTW). I noticed that the 2F dizzy had no condensor or ignitor connected to it. (Probably stolen over the years.)
Finally, I am running a weber and have already painted and replaced my side cover so I would prefer not to do that again or dimple it to accept a 60 dizzy (although I understand this is a favorite too)
So name the dizzies. There are 7 and a half up there. I am most interested in figuring out the true vintage of the ones I have of course.
Then of the two, if I was to throw in a pertronix, which would be best to do that in, Vac advance or vac retard. Or am I the retard and should drop some change on something else and post these in the for sale section.
