Wiper Blades?

[Cteufert]

I have tried a couple brands of wiper blades on my 65 C20 with no luck finding any that stay on. I have had the truck only a few weeks but since I've been taking it to cruise nights I figured working wipers should be among the items taken care of.

So far every one I have tried is too loose to stay on the wiper arm. This past week I figured the wiper arms were wrong so purchased some replacements but still have the same problem. The arm is too narrow and thin to have the pin on the arm stay in the wiper. I double checked for missing adapters in the wiper packaging and verified the wiper is the one recommended by the manufacturer.

So what does everyone else use? or should I start making an adapter to be able to use the ones I found already?
