1993 Chrysler Concorde Wiper assembly Parts

1993 Chrysler Concorde V6 Front Wheel Drive Automatic 177000 miles

I bought the car with this problem. The wipers assembly is broke. The plastic clip the snaps onto the motor arm ball has broke (I'm assuming). I've tried to snap it back on and doesn't fit right, or stay on. Chrysler sells that lower arm for $70. Is there universal plastic clips out there? Or will I have to just buy the lower arm chrysler sells. I can't figure out how the joints come apart, they are plastic and look easy to break if I go at it wrong.
