Can you adjust the 1968 Oil Pressure Gauge

My sensor is new and "working". The needle in the gauge moves (left to right) as you would expect when the engine starts. The challenge is the needle rests (when engine off) up at "11 O'Clock"), rather than at 6-7 O'Clock where the letter "L" is on the gauge face. As the engine runs, it moves down to the L. Anyway to reset the starting positon of the gauge's needle? Thanks

Does it rest at the 11 o'clock position when disconnected from the sensor?
Great question...should have added this in the post. When it was connected to the old (bad) sensor), it rested at 7-7:30 on a clock....slightly to left of the "L" letter on gauge. To test the gauge BEFORE I invested money and effort on the sensor, I disconnected the lead to the sensor and grounded it. The needle moved all the way to the right by the H letter on gauge face. So I felt that told me the gauge was good. Swapped out the sensor, had to get the extension piece off the block cleaned up and now the gauge seems to accurately measure the change in pressure when you start the engine....just that the needle now starts at 11 O'Clock.... Appreciate any thoughts
