RV-7A Slider Measurements for a panel mockup

I am about to start planning on a tech refresh of my avionics with the Garmin G3X. I was wondering if anyone out there might have the dimensions of the panel, subpanel and ribs for a slider. I would like to build a mockup so I can layout the positions of the LRUs and the wire lengths needed. This will allow me to build the harness in the comfort of my dining room table rather than on my back in the cockpit.

I think you can download a panel DXF file from Vans.

ok, panel to sub, 8 3/4" sub to firewall 14 1/2" center rib to pilot side rib flat to flat 9" copilot side rib to center rib 8 3/4"
