I got a set of Bosch windshield wipers in a package labeled for early 126 models (but not SD!). One is marked Li(nks = left), one is marked Re(chts = right). Other than those markings, I can't tell them apart. What's the difference?

And how #$%! hard is it to get the clips to snap into place? The old ones came off easily but if I pull any harder getting the new ones on, something's gonna break.

Aas I understand it, the left and right wipers are marked so as to the curvature ratio(?), one has a tighter radius.

I haven't had any issues replacing them.
