Find a NAPA store- - - -they either have a lot of the old stuff in stock, or they can order it on short notice. Have you done anything about those widowmaker wheels yet? If it's got a Hydrovac brake booster, that's a possible place the fluid is going. They're bad about leaking fluid into the vacuum chamber and never showing an external leak, and rebuilding one is a real pain! Fortunately, they're not too expensive as a rebuilt exchange unit. If the wheel cylinders are leaking, there will be wet brake fluid stains on the inside of the front tires, or between the rear duals.
