Mark That plane is just too pretty
It makes me jealous - I mean mine is good but everything I have seen on yours looks - well, perfect. One thing I recommend you change though is the subpanel extension beyond the throttle and mixture knobs. I had mine about like yours at first and it became a knee banging problem for both my wife and I and it became down right uncomfortable on long flights. I can't see anything in your installation that requires it. I cut down just the front plate and left the mounting flange of the aluminum angle at its original length so the mounting interface was unchanged.
