USA Trains tank car coupler plates

Have just received 3 USA tank cars and they are all missing the coupler mounting plate

I like to body mount and these plates give a flat surface for mounting the coupler

Any ideas

Call mike in parts at USA Trains?

Thanks Greg

Where are they located so that I can try and not ring when it’s nighttime[#oops]
