Don't exactly know what it is called but I broke the leading right at the base. It is mounted to the intake manifold and wired to the coil. I would be open to a new universal one if anyone has a suggestion. I did find one on ebay but there is no way I am paying $87 for it. Thanks

Mine did the exact same thing, lead broke off at the case of the condenser (capacitor). Never replaced it because I could never find one to match.

If you don't listen to AM radio you really won't need it, if that's any consolation. It is there to help cancel noise spikes in the +12 volt system that are generated by the ignition coil. These noise spikes can be picked up in the AM band but are not a factor in the FM band.
 
My local parts store had them in stock, same part as GM and Ford. I recall it being around 10-20 dollars CAD. That was a decade ago though.

Thanks I have converted my original AM radio so I never listen to the AM anymore. I was wondering if there would be any noise on the FM channels. I am still working on putting her back together from pulling the heads.

I probably have a few good used ones Mike if it turns out you need one.

It is just for some ignition static on the AM band, and even then I don't know if it really makes a lot of difference.

Should NOT affect the FM band at all. FM stands for Frequency Modulation which means that the radio carrier frequency is modulated (or changed) by the voice signal in the "frequency" plane, (which is horizontally).

AM stands for Amplitude Modulation which means that the radio carrier frequency is modulated (or changed) by the voice signal in the "amplitude" plane, (which is vertically).

Noise spikes from the ignition and/or alternator on the +12 volt DC wires in the car are "vertical" noise spikes and are detected exactly the same way "voice" signals are detected in AM band systems. That's how you get that "crackling" and "popping" sounds in the AM band. If you remember back in the day when listening to an AM station during a thunderstorm in the area, lightning strikes would cause major noise on the AM station. It's basically the same thing with the "noise" generated by the ignition system as the noise generated by the lightning from a storm. FM is immune to this type of "noise" and by design it ignores all of those electrically generated "spikes". Hence, no noise on FM bands.
 
I have two of the factory radio suppressors that would sell....
The Part Number on them is 2197674

Motorola use to make a kit for all three suppressors. Can find them on ebay from time to time. That capacitor is .25mfd at 400 volts (for the big spikes) if memory is right.
