Marx Truck/Coupler Replacement

Hi all - New to the forum and getting back into HO. I have a Marx caboose that has truck mounted couplers and doesn’t match up with the rest of my cars. I went to the KaDee site for conversion and they don’t even list Marx as a conversion item. Anyone have ideas that could be a substitute? Thanks.

Welcome.
