I have a 440 thunderchief it hadn't run in near 15 years sad I know but I'm giving it love and got her running and driving for short times before I lose spark in one cylender. I'm trying to fine a suitable replacement for the coils I've found them on ebay but I'd rather sorce them locally if possible the current coils are Bosch 0212940001. Its probably worth mentioning the engine is the jlo rockwell 2f440-4. Thanks gents
