I also fit some new spark plugs and HT leads and a new distributor cap as the contacts in the old one were in a bad state. The inside of the distributor was a bit of a mess too and when I went to set the points I couldn't budge the points set screw as it had been worn off by the PO.
Long story short, I took the whole base plate out and used a screw extractor to get the old set screw out. I then ordered a small set of replacement Lucas 25D distributor screws from a Classic Mini spares place for about £1.50

With the base plate out I could clean it all up properly and fit the new points before refitting it and setting the contact breaker gap correctly.
