Alternator: 88-89 Camaro / Firebird TPI 105 amp (GM)THIS IS A GENUINE CORRECT GM AC DELCO 105amp ALTERNATOR. not an after market copy or something else that may "Visually Fit" but shortly after may be found responsible.. when its too late.. as has happened having interfered with the other or inbuilt electronic requirements for this evolution of alternators.
