Up for sale a new high performance "deep V" alternator pulley with nut and lockwasher for Chevrolet Corvette , Camaro, Chevelle , Nova , Firebird , 442, Yenko classic cars . It is a nice alternative for the pulley # 3829387 and # 3846180. Used from 1963 to 1972. The dimensions are ID 0.669 in(17mm) OD 3.252in (82.6mm).
