Power brake conversion ? Factory stock booster 1966

[Flthead]

Have factory power brakes on a '66. Already converted to disc front can I use factory '66 booster with a '72 master cylinder an proportioning valve from the '72. Just curious if master will bolt up an work on stock booster

You should be able to use a '72 MC that was for a power brake application. Should bolt up without any issues.

You will want to check to be sure that the intermediate pushrod is the correct length for the master cylinder.
