This mod looks like it would be incredibly easy to update as is, by just modifying the version number. The mod license is MIT, so anyone should be allowed to do it.
All this mod really does is create an equipment grid for each vanilla vehicle (car, tank, locomotive, cargo/fluid wagon, artillery wagon) using the grid dimensions in the settings, then uses a for loop to apply those grids globally to every matching vehicle type in the game, with a small compatibility list for Bobs, Angels, AAI, VTK, and HeavyTanks to use the tank grid instead of the car grid.
For a more balanced/customizable replacement, I would recommend this instead to enable vehicle equipment grids, alongside this to customize the grid dimensions (if the defaults aren't to your liking).
In addition to having separate grids for each vehicle (so aircraft aren't sharing grids with cars, and differing tiers of vehicles will have differing grid sizes), it also adds vehicle logistic requests (so they can request ammo and fuel when within a network)
