Joe,
I usually trim the standard Kadee box when I want or need to fit a medium shank coupler. But the MTH SD45 is so tight that won’t work. Only a short shank coupler and small draft gear box fits (unless you remove the truck boss). I’ve used 806s on the SD45s, but MTH designed the pilot with the coupler pocket much too low. I want to switch them to an offset coupler to remedy that problem, but the Kadee offset model has a medium shank. I’ve been meaning to cut the truck boss to swap in the new couplers, hence my interest in Dave’s experience.
