1. remove the rotor
2. remove the 2 blue screws and with a little gentile wiggling you can get the vac advance out of the dist.
3. lift the primary lead out of the housing
4. remove the 2 red screws
5. lift the breaker plate out of the dist

from there you can find out what is wrong

Red arrow is the adjusting screw
Blue arrow is the pickup pivot
green is most likely the pivot post
There is another plate under this part that will come out as a unit when you remove the previous photos red screws

the green arrow points to where the two parts of the breaker plate pivot about
