I just use whatever refills the local parts store has, like the Anco's, Bosch, or something similar. Most of them come with a generic adapter, so you'll need to leave your wiper arms in, but remove the blade assembly at the pivot point so what you're left with is the armature that has the end shaped into a U-shape. That U-shape fits into the universal (usually plastic) adapter that comes with the refills. There is usually a release lever that lets you slide the old blade assembly down and off of the U-shaped end. Then you reverse the direction, pulling the new refill up onto the U-Shape end until it snaps into place.

I'm not sure if I even had the originals on when I got my truck early on but I'm pretty sure most of them come off the same way. There's some sort of release lever. Worst case, break it loose with a flat head, but take care not to damage the main arm that's attached to the truck, the one with the u-shaped end on it.
