I have a similar oil pressure situation on my very low mile 59AB. I bought a new sender when the car was restored and am using the original gauge. Like you, I posted my low oil pressure concern here and a point was brought up that the sender I purchased may not be correctly matched to the original gauge...if I remember correctly, there's a 50psi and an 80 psi sender. I found the original sender and will swap it once I get the car out for the season. I don't have a mechanical gauge but could add one temporarily to compare readings. Just a thought.
