As far as I can tell the RHD models have the same seats as the LHD models. when I first saw those I thought Dodge neon seats but thats not exactly it either. Hope someone can chime in and let you know what those are.
You can also try to contact IGGEE customs and see if they might know what make/model those came out of Others Front seat only [OTR0001]
I have these IGGEE covers and I swear by them, they are the best covers I have owned. waterproof, and no fading even in the Florida sun.
