I have the Pertronics Lobe Sensor, I don't know if it makes a difference as it senses the points lobes directly. The unit does not give any specifications other than maximum amperage based on coil voltage and resistance. I found the literature to be less than thorough, though the product works great.

I will try to find a shim set. I believe Accel / Mr. Gasket sell them. The shims should be common for all Delco non-HEI distributors, correct?
