Radio noise and carpet
I have a 48 club coupe with a push button radio. The radio works and can be tuned to stations. However it has loud spark plug noise. I have checked the plug wires and they are all flexible and appear almost new. I checked that they are firmly pushed onto the plugs and into the distributor but all are tight. The antenna lead is new and the antenna lead is pushed firmly into radio and antenna is grounded. What else can I try? I seem to recall that resistor plugs were used to suppress plug noise in Chrysler cars. Does anyone know the number of a resistor plug?
I want to replace the carpet. Can anyone recommend a source for carpet?
Regarding the radio noise issue, I am not sure if your '48 is the same as my '56 and '59, but on my cars there are condensers that are supposed to cut down on that excess noise. Off the top of my head, I think there might be one on/near the coil and then also on the generator and possibly on the voltage regulator as well. That would be a good place to look for an issue that's cheap and easy to fix.
Regarding the carpet, I again am not an expert on the '48's, but ACC (Auto Custom Carpets I believe is the name) is generally the go-to place for the 1950's and 1960's cars. It would be worth a call or email to them to see if they supply for your car.
I hope this helps.
Could also use the Autolite 306 spark plugs but gas at 35 not the regular 25. These are resistor style plugs. replace the radio static condensor on the generator it just might have wornout. Can get then at NAPA.
