I apparently did some uneducated ordering. I am going to order the Mopar P4529751AB. I don`t understand why Hughes does not make a flex plate that will work with their convertor.

Not sure but I don't think they make flexplates at all. I guess they assume you'll use a Mopar flexplate that'll work with their converter.
