e-clip size for distributor vac advance

[WheelHorse]

Anyone know the proper size for the e-clip in the distributor that holds on the vac advance arm?

This morning I'm just about the work and I go to step on her and she's a DOG.

Watching my AFR it was fine, but it took 1/4 pedal to creep into the lot at work. Let it cool off, popped the distributor cap and low and behold the e-clip was gone and the arm had pushed the magneto full retard.

Being an old Ford, I rigged something up, but I'd like to get the proper e-clip at lunch time if possible.

You have a magneto? The vacuum advance arm on Ford distributors fits on a 1/8" pin on either point or Duraspark types. The groove that the E-clip fits in is a smaller diameter tho, but I think one made for 1/8" applications should work.
