Something I've been thinking about for awhile, and might make a winter project: Switching to later SC or Carrera struts (mine are the Boge of that era), to get the larger M calipers on the front. I would keep my 19mm MC at first, and see how I like the pedal effort and feel. Anything I should watch out for?
yes, 19.05 was used for most of the pre '77 911s

there was a 1 year early 69 911 that used a 20.5 mm mc Porsche # 901.355.012.04, 911.355.012.02 updated version,
ATE # 3.2120 - 3901.3
but these are very difficult or impossible to come by

changing from the M/M to A or S/M doesn't change the hydraulics at all, so for performance use going bigger than 19 is a good and 23.8 is a bit much for most users
