I think the relief cuts (rebates) in the side pieces should be about 2mm deep.

The idea is that they provide clearance for the screw heads that protrude from the sides of the empeg, so you could measure the screw head projection distance and use that if you want a better number.

Oh, and the long slots at the rear of the side pieces should be about the same depth as the rebates you can see on both ends of the back insert.
