I need a rear wiper blade and I'm sure the facelift cars use an aero blade rather than a frame blade, do the aero blades fit the older arm or do you have to change that as well ? 2008 G4 RRSport TDV8 current
2009 TDCi 90 current
2018 Discovery 5 HSE lux current
1994 Dakar current

I just replaced mine with the bosch one from euro car parts, but rather than replace the arm etc, i swapped the blades over. So instead of £40+ from the dealers (complete unit) It was about £5.31 and works perfectly.

I think if you want to go full aero type it needs a new arm as well
