Whats a few cm between friends?
IIdo not have the answer you are seeking, but am willing to offer some advice, unless it interferes with another component allow for some "creative freedom" when fabricating these items, I myself was stuck on the MIP as the free CRT's I had available would not conform to the standard 737NG five display layout so I had to settle for four displays on two of my sims, and other dimensions you will have to just extrapolate and or modify, I hope the 2 Cm difference does not hold you up for long.:D
