I have had similar problems with the long and short cap and rotor arm. I would like to ask if someone could clarify the part number for Delco parts that provide a matching set. I noticed that most supplier list the rotor arms and caps but they don’t provide any matching information. I had to bend up the contact pad on the rotor arm to reach the centre electrode in the cap. So the centre pin is only contacting the very edge of the rotor arm

Thanks and best regards Chris
