I have a box of 25D Lucas Dizzy's. I was tempted to do the same as You. But found for $140 I could buy a new one from "British Parts NW". This I did because I am lazy. But not sure I got a good deal. The vernier timing is notchy. The marks that should be on the vernier are not there. It seems to work OK. I static timed it. Will have a better mechanic time it and set the carbs.
You can do no better than take advice from Morgan Spares. Robert Couch (Founder of Morgan Spares) tuned my TR engined Morgan each year until He died. My Morgan was always in the best of form.
