www.panteracars.com there is a guy who makes them and sells them or ask and the Austrialian Cleveland Guys definately have them www. ausfordparts.com
Couple thinsg to keep in mind ... running the motor without that brass bypass will overheat the motor ..also the water pump for the C motor is unique .. Elelbrock is the only co that makes the correct one ..wieand is the wrong one even if they say its right.
