DEC BA11-K KY11-L mounting brackets -- how?

Hi all,

I'm reassembling an PDP-11/34 in a BA11-K chassis right now, and am a little puzzled by the front mounting brackets (the ones that hold a KY11-L of either sort on the bottom, and a half trim-panel on the top).  In particular, on the bottom half, the available place for screws to go to attach the bracket to the chassis is nearly completely blinded by an overhanging tab.

The engineering drawings I've seen are unfortunately not very clear on this...  Anybody have an 11/34 in a BA11-K and care to take a peek and tell me how the hardware here is properly configured? (Hex head instead of DEC's ubiquitous Phillips truss, to allow tightening from the side?  Machine screw from back, and a nut on the front?  Other?)

    cheers,
      --FritzM.
