The main difference between the 63 and 69 pickups would have been the number of turns in the wire and the base being grey not black. There seems to be nothing that lists what the magnets were each year (though they usually say that the magnets varied due to the cobalt percentage being different). However the real man to speak to on this would be Tim.
Somewhat OT, but it is my theory that the number of turns in Fender pickups really varied more from individual pickup to individual pickup rather than from year to year.
Maybe there were broader trends in manufacture, but from what I can tell about how Fender operated it wasn't like they decided "OK, for the 1963 model year we will produce Telecaster bridge pickups with 7735 turns of wire to get a more Bakersfield sound. Esquires will get 7300 turns to save on valuable wire."
Sometimes you see citations to Seymour Duncan's website where average numbers of winds for Strat pickups for a given year are listed, but those figures are just that, averages.
Correct me if I am wrong, this is just my theory.
