Prior report was that my speedo was jumping with a arc about 10mph. After a while on the road it would steady out.
The consensus was that the grease/oil/lube that was in the cable was impeading its movement until it got warmed up.
Craig checked and found from an old cable he has that the actual cable will slide right out (after removing the gear at the trans end).
So I did so. Jacked up the car. Removed speedo cable and removed gear. Removed the instrument cluster and just pulled the cable out. Next was a flush of the hollow cable housing with acetone and then some thinner. Blow some air down through the housing and let dry over night. Next I used some graphite oil coating the cable as I re-inserted. Rubber band on cable was so I wouldn't lose the washer. Re-assembled everything and went for a drive. Speedo needle is pretty steady now even at low speeds...well as steady as a old fashioned wire cable can be.
