So I drove over to Summit Racing and picked up a new alternator because the one I had looked old and was not chrome. While I was there I went ahead and picked up a new adjusting rod so I could get it closer to the valve cover and not so far out of the frame.
I also picked up the new crank and water pump pulley which are polished and powder coated silver\clear. The crank pulley went on great and looks great. The water pump pulley on the other hand does not fit. So even though Summit sells it as a Chevy water pump pulley it will not fit the water pump on a motor out of an 89 Corvette.
I can drill it out and get it to work but would rather just have one that fits right to begin with. But it looks like March Performance does not make one that will work.
