a couple of years ago I changed my headlights to Euro but kept the original headlight wipers. I just swapped them left with right and they worked fine for some time. now both are dead and I want to get a pair of wipers for the Euro lamps. from what I hear installing them will not be easy and will require drilling some holes under the headlights in order to place them in the right position. has anyone been through this? is there an easy way to do this or is my mechanic exagerating and it's just a simple swap? thanks for any feedback.
