A point of reference. The MPC, Section 21 pg 2, indicates that 378773-S2, a 12 point head drive, was used in 65,66, and 379027-S2, a hex head drive, was used in 1967. No "early", "late" or changeover date reference was included.

I don't disagree what the Ford book might say BUTTTTTTT the real world is sometimes different as we have learned from other examples. As Special Ed (Meyer) likes to say "That's just the way it is" .

It was true at least until November 2nd 1966... My original date-correct, example pictured below

+1 or is it 2.  The MPC or that version of the MPC is  incorrect on this detail

We've shown  unrestored examples of the detail in a number of prior threads

I'm in contact with Jim Cowles.  He did mention I have a 65/66 and a 67 caliper.  He is going to square me away on what I should have. 

These are the stories I discover where I wish the kar could explain to me why or how...

The boots for the pistons are very much different from 65/66 and 67, as are the pistons, IIRC.

Have you found any date codes on the calipers?

I found one on the 12-pt bolts. Decoding I think 265 day of 1965 which equates to 22 Sep 1965, about one month before my build date.

Jim Cowles would know, he's rebuilt/restored a ton of these.

We need to encourage him to write an article.

Right!

Casting shows 284, which would be Oct 11, 1965.  Remember that the date on your door plate is a 'scheduled date' and can be off days/weeks before or after.  Other dates on sheet metal and on components throughout the car can usually narrow the date down to something more realistic.
