I have a really silly question, but can someone please confirm what the wiper blade lengths should be on a right hand drive (uk model) crossfire?

I fitted the replacement cowl cover, (apparently it's called a Scuttle cover here) and refitted the wipers, as bluecoupe pointed out my wiper was overlapping on the passengers side (remember uk model the opposite side), so I swapped over and now the drivers side is overlapping the windshield trim.

My Drivers side wiper is 50cm, and passenger side is 53cm. I see this is correct for americans but is it the opposite for right hand drive models?

Thanks!
