Rebuilding S400/500 query

Youtube has videos showing how to take the striker housing off the valve housing but none on rebuilding.
It looks like there is no location lug or pin to ensure they line up.
Am I right in thinking you leave the large central bolt that screws into the striker rail slightly loose until the six bolt housing screws are in place, then nip up? or is there any other trick?

Yes Peter, just leave it slightly loose, and nip it up when all the other bolts are home. Rog
