Any known wiper blade adapters for pantograph arms

[astrnmrtom]

So far I've been able to do some whittlin' on regular automotive wiper blades to get them to fit the bolt-on attachment points on my '98's pantograph wiper arms. Has anyone found and used an adapter that might make modifying the common wiper blades unnecessary?

Thanks,

All the blades i replaced on the school buses, i wish there was an adapter, but sadly i have never seen one.

I buy the Costco Michelin ones 24" $7.00. I remove the existing adaptor which leaves a thru hole and put the pantograph bolt thru it and the nut. ???
