They are not original for Peugeot 308 but they come with 10 adapters. I have tried to replace it on driver's side, I replaced in 2 minutes but with the passenger side, I had a problem
The wiper arm has a "tooth" that prevents me from mounting the adapter/wiper correctly. That tooth is on the opposite side of the wiper on the driver's side.
Driver side arm:
Adapter is not symetric:
Could I cut/break this tooth? Can I expect some problems if I ever decide to put the original ones?
