Automotive Wiper Arms...anyone using them? Thanks!

[GW]

Does anyone have a correct fitting automotive wiper arm that fits Grady's? I'm guessing this will be an older 70's or 60's type arm. I have a Gulfstream and want to convert to this type of arm/ blade. I'll have to swap them out more often, but, the current blades warp in one direction after about 4 months making them annoyingly skip when activated. Thanks for any insight!

My, those marine replacement blades are expensive. I tried finding, and making just a refill blade, but never had any success. Went to the junkyard and grabbeb a arm from a s-10 blazer and cut off the last six inches from the U. Drilled two holes thru it and the Grady wiper arm and bolted. Just happens my Grady used a 14 inch arm as does the Chevy S-10 Blazer. Sure, the arm and blade are not Stainless, but sure is much cheaper, and easier to find.
