mines a 69 429. just had new presseure switch fitted a few weeks ago.

i would say that when the car starts the needle points about 1 o-clock, it goes up about 3/4 of the way towards 'high pressure' . not between the drivers door and 'L' more like etween the passenger door and 'L' if you understand me. when the car heats up and im driving around it just stays covering up the letter 'L' too
