The upgraded newer-style, one-piece, frameless wiper blades with the newer GM special "pinchtab" mounting system are available for the 07+ Silverado. "Trico NeoForm Beam Blades" come in the required 22" length and required "pinchtab" mount. (They also come in the standard hook mount for the 07 classics and the 99-06's) They install easy, wipe really well, are super quiet and look great. They're available online at a very reasonable price. Hope this helps!!
