OK, so I want new wipers. Mine squeak and make funny rubbing noises when I use them, even after I Rain-X the windshield. I don't know if I should just get new blades or buy whole new wipers. The arms that hold my blades are a little ratty looking. There is some paint loss and a little rust.

It looks like the left wiper is longer than the right one too. If I just buy blades does this pose an issue?

Anyone have any suggestions?

Thanks - Bart
