The matching footrest availble for the rubber strip versions is for left hand drive cars. There isn't one for RHD, I checked when I fitted these to my car. The LHD footrest will not fit directly to RHD as they are totally different parts.
I *think* the GT pedals with the dots and the GTA pedals are the same (I would check part numbers to be sure). They sure look identical.
I've never seen a GT with the matching footrest though. Might be related to a reduced spec on the GT or maybe it will not fit, I don't know.
