I apologize for tha lack of images. Thesamba is not loading them right now.

Distributor mounted, no end play. Part removed, it had slightly less play
than a higher mileage spare dizzy. Possibly heat damaged rotor has a dull
plastic finish, older used one has a shiny appearance. Dull finish rotor
resitance: 1095 ohms. Shiny rotor: 1155 ohms. A tiny tiny amount of wobble
was felt between dizzy and mount hole. I cleaned a tiny amount of debris
from vertical facing edge distributor seats at. Horizontal face at hole was
clean.

The centre contact at low mileage dull finish cap sticks further out (down)
and pulling gently on it reveals a weaker spring than spring on spare
new shiny finish cap.

Par numbers on each cap and rotor are the same save for a 2 digit number or
x.x number.

I'm wondering if the potential issue (heat damage) is due to difference in
plastic quality.

Neil.
