I was trying to work out what displays are interchangable and a part of that is what interposers are interchangable.
This is a good picture - essentially showing how similar the 755c and 370c interposers are and how different the 755CE/CX/CD interposers are:
370C at the top
755 CX in the middle
755C at the bottom
Here you can see the 755C and 370C interposers along the top. Despite one connector (for the trackpoint) having a different colour's friction lock, I tried the 370c interposer in a 755c machine and it worked fine.
