94 GMC 2500 Sierra SLE 4x4 I've searched threads but most have been about the wiper motor. My issue is the wiper blades need to be replaced, my blade arms do Not come off, local auto shop wiper blade book shows as a replacement piece of rubber... conveniently no longer available, or at least not through the big chain stores here. Truck Parts and Truck Accessories for Chevy, GMC, Ford and Dodge Trucks from LMCTruck.com Thought this would be the place but only offers the kind where the blade and it's housing "unclip" from the wiper arm, not my type. My question is can I buy a total new wiper arm where I can buy blades at auto zone and put them on as needed? Is there anything special I need to know about the spindle where I attach the arm... thinking of checking pick-a-part and pull one off a newer GMC or Chevy. Will this work? Recap: My wiper blade itself is bound by a rivet of sorts... it doesn't come off in order to attach new blade from say auto zone. Looking for info on changing to a more up to date one. Thank you.
