Default Replacing a vacuum advance can

On an MSD distributor.....any idea how to remove it/install the new can? I removed the 2 retaining screws. How does the pickup plate get lifted up to allow the advance rod to come out? Do I need to completely disassemble the dizzy?

Pull it apart.Mark the gear relationship to the shaft first.

MSD website shows the exploded diagram.

I could be wrong, but I don't believe you have to take it apart. There was a trick to it. Maybe rotating the plate C.W. just enough to clear the rod end.

Up date edit: I believe it was someone on this forum that wrote, if you apply vacuum to the canister with a pump, it helps clear the rod assembly just enough to remove the unit. Same way going back in.
