Door locks, trunk locks, ignition lock cylinders....

I found that I have 4 or 5 trunk locks with keys for them.
Door locks...Maybe 6 or more loose in a box and several still in spare doors stored up the hill. I have several ignition cylinders with keys and some without.
I am tempted to pull one door lock cylinder apart just to see the guts of it.
Trunk locks are the easy part. I don't mind buying new since they are a stand alone part with their own key.
I just thought that I'd see about getting door locks to match ignition cylinders to have matched sets for the cars.
The 4 door is a 1969 model and I understand that the ignition switch and lock cylinder are a one year only setup?
