With the help of one of my new co-workers Jay, he figured out what I was doing wrong with the wipers. Turns out you need to make the copper tubes long enough so they fit into the wheel box (the bottom part of the wiper posts). What this does, is to connect the wiper motor and wheel boxes into one solid assembly, so instead of the motor rocking back and forth, it can't, because it's hard mounted to the wheel boxes. Now, the wipers work great, and the only thing left to do, is drill a hole for the switch in the dash and clean up the wiring under the dash.

Jonathan also stopped by this weekend to help, and we managed to get the side view mirror positioned and installed, as well as installing the trim plates on the windshield.
