This is GENUINE.. KEEPING YOUR CORVETTE CORRECT.. not a "Bitsa".. going cheap here is pointless.....

This is a ONE year only 108 Amp GM Upgrade replacement alternator for the ONE year only application.. 1985 Corvette....BUT as it has not thread at the top ear.. its been know to be fitted to 84's also.. .. so check yours does NOT .. NOT have a threaded ear mount.. the smaller adjuster mount and  your other specs are like the image which IS CORRECT.. and your laughing....!...

• These USA Delco units are outright supply, no exchange needed.
• This is a 108 Amp standard replacement GM Delco alternator.

  We do our best to carry EVERY year of Corvette, Firebird & Camaro Alternator in stock for immediate replacement and minimal down time- but only every quality GM Delco units..not unknown reproductions etc.

  NOTE: We do NOT allow returns and exchanges .. it must be right the first time. NOBODY gets an alternator that somebody may have tried or played with or pulled apart and switched critical internals.. (yes.. it happens....!). Be patient..vin details needed and images of what you have front and rear.
