Late 124 passenger-side lower dash removal?

[Jeremy5848]

I'm trying to remove the lower dash on the passenger side of my '95 E300D (W124, OM606NA0 so I can access the vacuum manifold for the climate control system. On pre-airbag cars this is easy, you remove the glove box liner and the valve assembly is next to it. The later models seem to be much more work as the entire lower dash panel has to come off.

Unfortunately, my CD-ROM FSM doesn't cover airbag cars (even though you can select "1995" as the model year) and my paper FSM is pre-airbag. In addition to the screws underneath (including a hidden big one that need a 10mm socket and long extension to remove) I've found 2 more screws under the right air vent.

I'm about to remove the center vent to see if more screws are hidden there. Anyone know if there are screws I've missed somewhere else?

The battery is disconnected and the SRS unit is unplugged (red plug/socket in passenger footwell).
