Dan:
If you start a new thread, some of us may miss the ending of this "good" story. I'll keep my $$$ bet on the TB coolant nipple on front of the intake

Where can I get one of these?

If no one posts where to buy a new one, try contacting Vette2Vette salvage. They are listed as a supporting vendor at the bottom of the left hand column of vendor names.
