Spark Plug Lead Set: 403 Olds 78-79 TA (Delco)
Genuine 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.....
