I now have three different sets of part numbers for the ignition parts for this tractor. The original 1960's numbers from the parts book. A second set I pulled off the forum and the newest - latest numbers based on the GP Sorenson web site.

This is the 'tune up kit' # 0236318 from Tractor supply, it cost $18 and contains the correct rotor, points and condenser for the autolite ignition system.
