Keep the condenser on the coil, helps keep radio buzz from happening. Be sure to shim the distributor shaft per the instructions if the distributor is worn and has a lot if up and down movement on the shaft.

Minimal up and down movement. Clearance for module to ring is in spec .010-.060. Did test the vacuum advance and it doesn’t hold vacuum or move at all. I’ve ordered a new one, but the truck runs fine so do I really need it working?
