I don't think they work on our GMT-900's, I believe ours are bracket-less.Get the wiper helper springs, too... They're worth the extra $10!
Especially for those with a wiper on the rear window...
I've never seen those before.![]()
The're springs that go on the hinge of your wiper arm to make 'em press harder on the windshield...
Works great for those higher speeds
And good for cleaning stubborn mud spots, as well![]()
They go on the wiper arm, where it's hinged... Usually a couple inches away from where it's attatched to the wiper motor... I'll go snap a pic in a few minutes for y'all
