I've got a 1 wire alternator off an '89 suburban that I junked. Alternator was on it for only 3 days. Guaranteed to work. It will fit at least the '87-'89 T/A or Camaro and maybe later models. Paid $90 and I am asking $50. If no one is interested, I will keep it for my '87 T/A if I need it. FREE SHIPPING within the U.S. If you have any questions, feel free to ask. Chris 330-204-4199.
