Ty,
These look exactly like the trunk hinges on my '42 series 75. The look is right and the length and hole to hole dimensions you give are spot on. However, I can't validate the numbers you give as I can't find any numbers on mine. I have a set off the car I'm comparing them to that I believe to be original and I can't find any numbers on them at all. I can find "LH" and "RH" markings in the castings.
Let me give you the interchange info on these in case they turn out to be the same hinge:
Part numbers: 4089541 (right side) and 4089542 (left side)
