The heat may have contributed to the failure as we were in slow traffic for 45 minutes and it was very hot. However the oil temp was at 180 which should be fine in the compartment.
I opened the sensor up with a vise and found a transistor that was connected to the base of the device at one end with screw and at the flat spot it looked liked some type of glue or substance between the back of the transistor and the base. The heat must expand the materials at different rates and cause them to separate and fail.

Not designed for the air cooled engines I suppose.

we have them in a 72 but I ordered new points from Pelican and will remove them.

Makes me wonder about other aftermarket devices like the MSD's. Can they handle the heat in the engine compartment?
