1. 1967 was the first year which used a different power/manual brake pedal. 1965 & 1966 cars had only four pedal types to choose from, depending on whether the car had Auto or Manual transmission, and Disc or Drum brakes.
2. The '65-'66 power brakes have a very short travel, but the excessively high pedal effort is probably due (at least in part) to insufficient vacuum.
3. Doug's pedal is actually from a '65 (or very early '66 carryover) -- that external rubber stop and associated mounting arm were replaced by a far more cost-effective pushrod retaining clip within the manual master cylinder and was entirely superfluous on the power brake-equipped cars anyway.
