Points, condensers and spark plugs. Did 100's of those in the day as a mechanic. They call the part's changers "technicians" these days. Most now, could not do an engine overhaul or valve job. They shop them out to a machinist.

I still own a dwell meter and timing light. LOL! I could still static time an engine, after an overhaul and have it start within 5 seconds.
