I actually have the following units in the Maule I crashed

So if I pull out the old audio panel (PMA 7000) and install the PAR200 I can pull the Sl30 out use the stand alone Val429 for the NAV 2 VOR/GS and because the PAR200 has a buildin 8.33 I pick up some shelf space with the Sl30 gone to properly install my VFR Garmin Aera 660 this sticks up above the glare shield about the same thickness as the SL30. So it’ll look like a custom fit ( see vid https://youtu.be/i80m-rVZWRE). Granted it’s a whole bunch of rewiring but worth it
