A few other points of interest.

This same process works for the Dura-spark distributor but you pry on the the reluctor to get it off. Don't pry on the teeth, but on the main body part, with two large screw drivers. You also need to mark the reluctor with the shaft because there are two grooves for the roll pin.

The width of the commonly used advance slots are as follows.
8L or 16 deg. .358
9L or 18 deg. .384
10L or 20 deg. .410
11L or 22 deg. .436
12L or 24 deg. .462
13L or 26 deg. .488
14L or 28 deg. .514

These seem the be in the pall park since it's not a machined part.
