ignition module heatsink compound should i replace it after 30 years?
another while im in there post--- ive read a couple posts here that the that the heatsink grease gets hard and crumbly and doesnt work as it should to transfer heat from the ignition module. is it a good idea to remove the module and regrease it with some new? i have plenty of heatsink compound from my computer shop i can use.

Sounds like a good PM practice to change it once every 30 years huh?
I took mine apart just to clean it about 8 years ago when I re-built the motor. I put it back together dry and have had no issues. Not sayin' it's right, ... just sayin'.

If it lasted over 30 years some people might say to leave a good thing alone. However, it probably is a good thing to try and conduct as much heat from an electronic component as possible with new grease.

I think the problem will come from the 2 wires going into the pickup coil. They act as a hinge when the vacuum advance works and one of them is likely to break when you pull them off to apply the new grease.

The pickup coil wires break internally from being flexed by the vac. advance. From what I have seen it is near the pickup coil not the module.
The wires can be soldered or replaced.
