A320 MIP CEN Block

Hello I am thinking of building a A320 cockpit at home and I have been making the 3d model on sketchup. I have been followeing the dimensions of both of these websites:
https://www.simucockpit.fr/a320/1-la-menuiserie/
http://www.mon-a320.fr/index.php?page=mip_menuiserie




My problem is that the MIP is supposed to be rotated 20 degrees and it is supposed to fit on that side (black arrow) but that site is only ~399mm and all the panels that I see on websites are like 420mm.

One of these websites even provides a drawing of one with 425mm that would go over and I wouldn't be able to assemble the glareshield. Where can I find the right drawings or what am I doing wrong?

I also found one on a cockpit parts shop and that one is 420 mm still wouldn't fit:
