Spark Plug Lead Set: 403 Olds 78-79 TA (Delco) May have cut off markingsGenuine Lead set for the 78 79 Trans Am with the Olds 403 in it. All correct length per lead, note that 2 leads that go on the spark plug have 90 degree end caps on the 77 403 models but this 78 79 will also fit ok. You don't buy these often in a ten year vehicle life.. you can change lots of other things but keeping the ignition ignition system at its factory best has some merits..
