New voltage limiter questions - 67 Dart 270

most of these plug in limiter applications had a paper like insulator between the circuit board and the limiter. Same 3 slots cut in a thin piece of some material ( razor thin phenolic I suppose ). Those would crack and fall away.
I don't know that you still need it. No other purpose than prevent short circuits where OEM limiter housing or that L shaped spade terminal from the noise cap' might contact the circuit board.
One of the very early Dart panels had a board mounting screw beneath the limiter ( how ignorant was that ? ). The insulator is absolutely req'd there.
A lot of members here will suggest that since a modern solid state regulator doesn't make noise, the noise suppression capasitor is no longer req'd. While that may be true under the electrical hat, it aint true under the mechanical hat. When you delete that second male spade you degrade the mechanical connection of the electrical. Because.... That girl has already been stretched to 2 boys. ( Here is another place for RTE to suggest, "bend the little thingy" ).
and btw as you dig the broken board pins from the harness connectors you'll notice those females aren't exactly round. Always have been slightly oval. A little bit of di-electric grease here will make them easier to remove next time ( we hope )
