So far only one picture and minimal information. Kilmartin sheet metal parts are generally reported to be quite good. The feature of interest in this case is inclusion of original style floating captive nuts that will accept screws to attach the shutface plate. Some of the competitors parts are missing these bits, leaving it up to the installer to figure out how to add these parts or otherwise work around the missing features.
