Re: 63 power brake conversion
63 is a one year only booster. #2574 is stamped on one of the tabs. Apparently it is not unusual to see passenger car units restamped with that number so be careful. The Master cylinder for non PB and PB cars is the same except for on PB cars they added a bleeder near the brake line entry.
The MC cap has a thumb screw on non PB cars and the thumb screw is changed to a hex bolt on PB cars apparently to provide some additional clearance.
