The Vette has more advance due to the aluminum heads allowing for it.  

As for hooking up the 3-wire (heated) sensor, just hook one of the extra
wires to gnd, and the other one to ign +12.  I have a part number for a
Bosch that was originally used in a chrysler that will work.  It is only
about $45 from Autozone, if anyone is interested.
