I'm having a hell of a time with my 1994 Camaro's windshield wiper motor.

I finally screwed the motor up enough so that I have to replace it....

However, I can't seem to get the bushing off that connects the motor to the wiper arms. Anyone know of a special tool that will help me. Honestly, it's not so much the taking apart that worries me, it's the trouble I think I'll have putting a new one back on.

thanks,
