    Distributor Vacuum Advance replacement

    Hello, I'm struggling to replace the vacuum advance on the distributor. I have a 1986 W150 5.2. The manual says to pry up a reluctor thingy as one of the first steps. I can't pry it up. It looks like it's secured with a snap ring inside a collar. Has anyone else replaced a vacuum advance...
