Spark Plug Lead Set: 403 Olds 1977 TA (aftermarket) This is for the shifterGenuine Lead set for the 1977 Trans Am ONLY 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 NOT on 1978 79's GM Lead sets.. the latter will also fit ok.. and may be better for those with hedders now fitted too 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
