securing pedal board?, can't remember what goes where Options

[Calwaterbear]

so on my 72 1.7 the board that goes over the pedal set was completely shot, i scavenged one from a junkyard car, then used it as a template to make my own out of plywood - and preserved it with several coats of polyurathane.

so time to put it back in the car - and I'm having trouble remembering how I took it out originally.

The 1/2 moon cutout on the left side - thats no problem it's held by the metal tab secured by the bolt going through it and into the threads on the floor.

and the scooped cut out above the clutch cut out - I assume thats for clearance of the wiring harness - correct?

can any one tell me about/ why the 2 oblong cuts on either side of the clutch cut out?

and on the right side? I have a hole there the size of a nickle, but its over the opening in the tunnel - I don't see any place to secure it - is there some sort of mounting system I am unaware of?

Thanks in advance
