I bought new wiper blades in Walmart, but found that the RHD ones are slightly smaller than the LHD ones. So, buying what the yanks have resulted in a slightly larger driver side blade which now reaches to the very top of the windscreen (and very marginally over)
Just checked back over my post on facebook group when i fitted them
"Dull heads up when you come to buy new wiper blades, if you check any of the American websites for wiper sizes they’ll say you need a 22” & 20”
I went and bought a Bosch Icon 22OE & 20OE, it appears RHD cars have 22” & 18” "
