Terminal post detail

Photos all link to higher-res images (800 x 600)
Assembled in distributor.

The fiberboard piece insulates the points spring from the housing.

Points spring is sandwiched between the terminal post & square washer

With outer nuts & washers, and points removed.

The fiberboard piece also insulates between the terminal post square head and the breaker plate.

The small plastic washer which fits the hole in the housing is removeable in this distributor.

I have another distributor where this washer is shaped like a grommet, and fits in the housing such that it does NOT come out.
