Does anyone have a toybox that could take some measurements for me? (x-post from 40 section) (1 Viewer)

I am looking at making my own adapters to shove a minitruck reduction housing into my drivetrain. It's the exact same concept that marlin does with their toybox, but since they aren't making them anymore, I can't get one. I guess the next best step for me would to be making some custom adapters to get one in. If anyone has one that is currently out, would you be willing to take some measurements for me?

Thanks,
