Got a question for you all. Might be tough but should work. Is it possible to make a copy of the ES44 NS Heritage cab and transfer it to the default ES44AC?

I really am sick and tired of it without that speedometer on the MFD display.

Not sure you need to make a copy of the whole thing.
I would start by aliasing it in the engine blueprint.
You will probably need to copy the lua script though.
