I am not sure which is correct, but a manual master from that year Corvette was $20. I see they are $34 now, so not a huge mistake in dollars. The unit I had could not be used with a power unit as the hole where you put the stem to push the master on a manual was pretty deep. There is a ring inside so when you push in the stem, it locks in place. The one on a power unit is shallow and the stem from the power unit does not lock in place.

With drum rear brakes, I would not use this master unless you have an adjustable proportioning valve. The disk style master pumps a lot of fluid to the rear and could technically pop the rear wheel cylinder. I had a problem on my car with disk brakes as the calipers on the rear had really small pistons and the Corvette master pushed too much fluid to those calipers.
