Not sure why the original thread was closed.
But I was inspired to try this myself.
A Digital Dynamics Motor Mite just fits. I would be great if the OP could post a pic of the Mini Commander install for comparison. I will need to grind down the screw post for the backup and marker light harness bracket, but will be able to keep the figures and grey interior cab intact.
My concern is the tight tolerance between the corner screw posts and the multi pin connector or any other metal on the board..
I was thinking of painting the outer rim of the boards with liquid wire insulation. or maybe use some other type of barrier like cardboard.
But as I write this it just occurred to me to paint the inside of the cab with the rubber compound.
Any thoughts or advice.
