Well thanks fellas. That didn't take to long. Yes, assembly line installed disc brakes. So the FoMoCo unit pictured is a service replacement and is not correct for this car. I should be on the look out for a Bendix power brake booster, crimped not banded with the check valve in the 10:00 o'clock position. Should there be any other markings ? BENDIX imprinted, part numbers, date codes or sheet metal stamps ? Should it have it's own mounting bracket/assembly. As mentioned a direct swap ? Brian
