I can't believe I just spent 20 minutes of my life reading about wiper blade replacements but like anything with tesla might as well learn it all. The short story is that you can get various 26" and 19" blades but the issue is the adapter to get them on the tesla. Some require clipping plastic.
But Bosch Aerotwin A102S appears to be the exact replacement for a model 3. So no hacking. But there are cheaper versions and also some sweet by silicon blades as well.
Any silicone blades that work? Far better, never wear out or dry out......
