Welcome to the forum. I've never seen a factory brake booster on a 62, it would be interesting to see the setup. Is it a conventional type mounted on the firewall?
In any event the drum brake master cylinder will not work with disc brake calipers, they are incompatible due to residual pressure valving, fluid capacity, and outlets needed for the separate front and rear hard lines. These are needed to accommodate the proportioning valve, which controls how much pressure goes to the front and rear brake systems. Generally the boosters must be used with the compatible master cylinder (disc or drum) due to differences in push rod length where the M/C attaches to the booster.
