Check to see if you have a local rebuilder? If that dose not pan out.... Call and see if you can send it to be rebuilt over at CARDONE?

Did you try napa? The one here in Chula Vista has it in stock I believe, $135. That might not be the correct one, but they have a bunch of different ones when I searched for 66 Barracuda. Some a lot cheaper too.
