Onboard computer light install PITA

Anybody else have major grief swapping out a burned out onboard computer light? Got to get some kind of screwdriver in a tight space behind the thing to unscrew it. The best arrangement I came up with was using a flex shaft on my screw gun but still a major pain. The second time I did it I was impatient, got the two screws out and then tried to bend it out to get the light out and the new one it. I did manage the switch but I broke one of the screw receptacles on the face. Still usable but when you'd push a button, it would tax the other mounts, finally a second one broke making it hard to push any of the buttons. Had to open the glove box and get my hand in behind it. Major pain.

I only use it for time, date, range, and temp but I like it for those. I had often wished they had just used a method of face mounted screws for easier access so I just made it happen all by my lonesome. Cut some high quality 3/4 birch ply into 5/16ths thick pieces and glued one on each side with epoxy. The screw mounts on the computer body have little triangular supports in back of the screw bracket, I ground those out of the way with my dremel so the plywood could go right up to it. I used the ply that way for less chance of it splitting, as solid wood might.

I used 1 5/8 black trim head screws through two strips of thin brass plate to attach it. I drilled the holes 1/8 dia, which was just a tad less than the thread dia, so as to avoid ruining the skinny ply pieces. I have a chemical solution used to antique brass, turn it from yellow to that anodized bronze color - useful in kitchen hardware repair. Blackened up the brass that way. Getting the thing in and out is now a snap, only downside is you need to redo a new/used computer as I just did owing to major drama with the older (failing) unit. Oh well.
