Narrative:
After making a mechanical 'write-up' for a discrepancy with my captain side eadi, I notified our maintenance to correct the problem. Upon first attempt to fix, mechanic inadvertently checked wrong instrument. I wrote up problem again. Mechanic finally replaced eadi, correcting the discrepancy. My problem is that the captain side inclinometer was not on the newly installed eadi. We flew to cvg and then the next night to cha. Myself, as did other crews, did not realize it was even missing until 2 days later on thursday. We did have an (first officer side) inclinometer, so the flight was never without a means to coordinate a turn or stalled engine event, but since it (I found out later) is not addressed in our MEL, it was determined both must be installed.
