Here's the used console I picked up. I think it's on its 3rd iteration now of being chopped up.

the previous owner had some big hardware in it so I had to build mounts for my electronics in the gaps and get back to flush with the console surface. I still have to fill, sand and repaint the black surface before installing my panels.

here's my dry fit where I screwed up the location of my tach guage

I had let it sit for a while in my CAD program and when I revisited it and turned on the steering wheel layer I saw that the wheel would block my view of the tach so I moved it closer to the binnacle throttle. Now I either have to reverse it and deal with the tilt/trim being on the opposite side or order another piece to shim it up. Or find a cup holder that fits that hole then set the guage between the 2 units on the upper panel...
