Restoration Correct Correct Fit And Finish Correct GM Part # 406172 Bushings wear from vibrations and normal operation on your 1972-1983 Firebird. As bushings fail, clutch can become inoperable. Suddenly one day the transmission shift level becomes a little sloppy and makes a slight clank sound when shifting into any gear. This sound does not come from the transmission itself, but from the external linkage. It makes the sound even if the engine's not running. So don't confuse it with possible drive train problems. The transmission will go into gear without a problem, but if left unattended to, will most likely wear out the linkage, to where selecting the correct gear could be a problem. Don't wait for complete parts failure on your 1972, 1973, 1974, 1975, 1976, 1977, 1978, 1979, 1980, 1981, 1982, 1983 Firebird.
