I did find the cap, rotor, points and condenser and they are on the way so hope to eliminate those as issues. Car has original parts is seems to time to replace these 40 year old parts anyhow.

You should measure voltage referenced to ground; they way you did it, the measurement was referenced to the input of the CDI. Reconnect everything, connect the negative lead of the voltmeter to a good ground and clip the positive lead of the voltmeter to where the red wire connects to the distributor.
