The chassis aligned without much difficulty. Actually, it was very much aligned; the adjustments were very slight.

Now I have to fix a lamp of the band 4 that does not light up (and it is the one that the wrong size though I do not see how that would cause it), and then try to align the shadow meter to get the dark sector in the middle (when looking at it the sector i way to the right, so I only see the left edge of it).
