Parts for 1960's / 70's Citizens are hard to find, its also very hard to find part numbers - there just isn't the same info/documentation around that there is for Seiko. I think Borel's might do some Citizen parts, but the best (only!) route to go most times would be to find a donor watch of the same model/movement. That's what I have done a couple of times, once to get the setting mechanism sorted on a Crystal Seven, and once to get a correct crown and second hand for a diver. The other thing you'll need of course is patience!
