OK... after ordering 2 of the Master Cylinders noted as "bolt on... need nothing...work great!"... on Bob Johnstone's Avanti and Studebaker interchange list...
Does anyone have a VALID part number for installing a Dual-circuit master cylinder on a 1964 Lark with Power Disk Brakes?
I have ordered:
Bendix #11323- the hole in the piston was too small for the booster's operating rod NAPA #36307- The piston in this master cylinder was not "deep" enough to accomidate the rod
