Well here is Plan A for the gauge locations. No layout I tried with only 2 gauges made me happy, so I put three holes. Tach, wideband and maybe a clock. Gauges in picture were just handy in the horde.
The headliner will follow a curve something like the lower blue line at right side. I'll probably tip a curved flange on this piece and make companion pieces to transition out to door top windlace at either side.
The bead rolled details more or less match the bottom of dash. The face may get some detail later, once the headliner location is mapped.
I'm happy with the visibility, it is right above the rear view mirror. I might in future angle them towards driver, just for the cool factor.
