I have an '89 Skylark and all of the window wipers, inside and out, have dry-rotted and cracked. Does anyone know in can get a set of new ones for all four doors? I've seen some on JC Whitney but am not very confident they will work on my car. Thanks.

Do you know the part numbers for the pieces you are looking for? If not, call a dealership and get part numbers. Once you have those, check on gmpartsdirect.com, or just google the part numbers and see what comes up.

I am assuming you need the window sealing strips for the window channel, and not windshield wipers?

If so then you can call the dealership and ask them, or visit Chevrolet Parts, Cadillac Parts, GMC Parts and Buick Parts powered by Nalley Buick GMC | Nalley Buick GMC Brunswick , and search for window sealing strips, you should find diagrams there that should help you identify the part/part numbers.
