Lon, I just sold one, new old stock in the box to Don Hyde in Plano, Texas. Let me know if you would like his contact info with a pm.
You can also get a new fluid balancer from "Snowbird" although I don't know much about these or have current contact info. Other guys probably know on here. I see his stuff occasionally on EBAY and has good Y knowledge.
If you check with CASCO or some of the other tbird parts suppliers-they have them, sometimes or can reman a core.
This is one pricey part in case you didn't know.
