The Novak website says that repairing a BA 10 is not worth the money. That's probably true.
Search for an AX15 (94 or later with the external slave cylinder) on Craigslist. Look at auto parts AND cars/trucks. You could find a XJ for real cheap. You then get lots of useful parts.
The cost to repair the BA10 could be more than a used AX15.
