David, are you asking how to remove the vacuum advance unit?

Disconnect the vacuum line. Remove the two external screws that attach it to the outside of the distributor housing. Then remove the distributor cap and remove the arm from it's pin which is attached to the moveable breaker plate. It may have some sort of retaining clip or possibly a machine screw. You can do all this w/o removing the distributor from the engine though it will be a bit of a reach.

Photo is from a 56 Delco unit but typical of most others. This uses a screw to retain the arm and a ground lead.
