Dale,
I'm sorry, but there's no way I can tell for sure.  The first ones I ordered
looked like they would fit, but once I tried them on a coil, they didn't match
up and had to be sent back.  Like I said, the parts man got a bit miffed at me
before it was all said and done.  You might be albe to go to a major GM
dealership and try some of what they have in stock.  Make friends with a GM
counter-person.  Or, maybe ask someone on the Corvette SIG.  A couple of days
back I posted the numbers of what I ended up with.  I do know that they work.
Coil p/n - 12558693 (AC Delco p/n - D581)
Connector p/n - 12126487  (AC Delco p/n - PT757) (These require slight mod.)
