Oh, a challenge, you say? Let's rock! The '65 shop manual says: Dimension a, to be measured from the tip of the push rod to the center of the attachment hole, is 5.649" or 143.5 mm. It may vary by 5 mm due to various tolerances in the frame. This measurement is only to be used upon replacement of the push rod and only if the original push rod can not be used as a measurement. The important measurement is to get 1 mm of clearance between the tip of the push rod and the beginning of the master cylinder piston hole. This equates to 5-7 mm movement at the brake pedal, which should only be adjusted by moving the brake pedal stop plate. Dimension a should never be messed with or else! :) My opinion: As to your 150 mm, this sounds outside the specified maximum so I'd adjust it only if you are sure some dumb PO messed with it or if maxing out the stop plate will not give a correct measurement, otherwise just try to use the stop plate.
