HEI Spare Parts

I'd like to order or buy some spare parts for the GM HEI distributor in my Dauntless. So far I've found the NAPA part number for the module to be TP45SB, but I'd like to find the other things you should carry. Other than the module, what else would be good to have? Does anyone know part numbers that I can take to the FLAPS and get these things. I looked at Rock Auto and went to my local Advace AP Store with no luck. I asked for parts for a 75 Buick Apollo and they just looked at me kind of funny.

Thanks,

 

I carry a new cap and module. We ran into a guy on the Rubicon that had spent 3 long days stuck out there because of a bad module.

 

I found that Auto Zone had parts for a 75 Buick Century with a 3.8 that I think are right. They mention odd fire in the product descriptions. They didn't show anything the right engine size for a 75 Apollo. All that said a cap, module and rotor would be enough? They also list pick-up coils and I think the main coil that's on top of the cap.

When I went to Advance Auto, they couldn't find anything for a 75 Apollo.

Thanks for the advice,

 

Thanks Warloch

 

Grease to put under the module?

 

Yeah, I'd say the module and dielectric compound are the two most important things with the proper tools to change the module. Some use an odd size screw head so make sure you have the right size. The coil pickup can go bad but it's so seldom I don't carry one. In 20 years I've had only one go bad and that was because the wires broke inside the insulation from the movement of the vacuum advance. They don't typically go bad. An extra coil, cap, and rotor wouldn't be bad but as long as you have the ground strap installed under the dust cover for the coil they don't normally go bad either.
Module is the biggie.

 

Is it that white heatsink grease?

 

Yup. Referred to as dielectric compound, dielectric grease, silicone dielectric grease, etc. Also minimizes corrosion between the module and distributor body. Commonly used between ignition wires and distributor caps or ign. wires and spark plug terminals. All the stuff I have used has been clear but I'm sure it comes in other forms.
