Replacement Wiper Blade for the Sims Cab?

[Searay45db]

On my little G1800 I have a sims cab with a wiper. The wiper blade needs to be replaced, not the arm, just the blade. Only thing I can find is the whole arm from Sims for $45 bucks. They are out of their minds! Anyone know where else to get them or how to modify a regular one to work?

Thanks

Help us out here since it's a Sims/tractor cab company. Not to many know what we dealing with! Pictures, mount style and length would be helpful.
