Funky wiper ?

[Zonecone]

Ok my project crew cab is throwing me for a loop. I bought the truck with some mods so not sure we're to start. I do no it's a 1984. Old owner put 91 suburban clip. Now I'm not sure if it's factory column or not. What's hopping is the washer fluids come on when wipers come on. I haven't turned them on till now. Iv been Workin on drop in it and cutting notching frame, and it's a project so it wasn't a big concern. We'll I want to drive it and it's now raining. Problem. Any help greatly appreciated.
