The GRT EIS-4000 engine monitor's default bezel is a little "old school" and didn't really match the decor. I found a replacement bezel from SteinAir that looks pretty cool!
Beware, however, that the EIS-4000's mounting holes are for #8 screws, but the replacement bezel is made for !! #6 !! Allen Head screws. I had installed #8 platenuts behind the panel for mounting the EIS-4000. When I swapped out the faceplate, I was forced to use the #6 screws which, fortunately, just catch on the #8 platenuts, but it would have been a lot better to have used #6 platenuts too.
