To answer my own question...I've installed the Pertronix Ignitor in my 1960 235 engine. The bakelite block has to be removed so that the mounting plate for the pickup can be fastened down.
Was amazed at the timing correction I had to make to get it back on the mark after installing the Ignitor. No noticeable change in performance as I retained my stock internal resistor coil and steel-core wires. Will add the points components to the 300 pounds of spare parts I normally lug around....."Be Prepared"...works for me!!
