Will add picture of Ford distributor converted to dual point dual coil.
It is from '64 Cams Valves Ignitions Hot Rod book.
In '64 book it has picture of Ford Transistorized nition Box.
Have to figure out what that is.Says it is good for racing and normal driving.
Says 'hotrodder's have stayed away from transistor ignition'.
Here is page with picture of Ford distributor home built with dual points for dual coils.
Picture is probably from '56 how to article.
