66 Dart GT HT Whatsitgonnabe?

Yes, a refurbed booster/MC setup is $128 on Rock Auto: More Information for A-1 CARDONE 506101

An even $100 if you turn in a core.

I may have to look into that then. Some of the rubber parts on mine are visibly dry rotted and have small cracks. At the very least if the canister halves on mine are in better shape than the cardone one, i can use the seals, diaphragm and pieces from it, to rebuild mine.
