Need starter hardware for Johnson

I have a Johnson 20R-70C and need everything but the starter, which I took off of a 30hp motor.
I think I have found that the 20hp did not come with the electric starter option. Any advice as to how I might attach the starter to a 20hp, as I am getting to old, weak and tired to pull the starter cord?

Later in the years the smaller midsize motors (25hp I believe) did have an electric starting option. After browsing the brochures for 1970 and parts diagrams for all models of 1970 20hp, there seems to be no mention of an electric starting option, The 20 is listed as having a "manual with automatic rewind" starting system. For this reason I do not believe there to be provisions to mount an electric start. I believe the 33 was the smallest of that year to have an electric option. (feel free to correct me if I'm wrong)

As much as I hate to say it, my suggestion would be to get a different (and likely newer) engine with an electric start, or at least an option so you can utilize the starter you already have. The amount of modification and fabrication needed to mount an electric start to this engine would be a lot of work and likely a lot of money.
