Thanks guys. Yes finding a swingarm was not easy, it found me. I had some want ads and it worked out well.
As for plastic. I sanded it with 220-320-400-800-1500 yes wet sand. Than buffed it a little. Wax didn't do much for me and still had a dull appearance. Secret recipe! Armoral haha yeah it made the olastics shine pretty decent. They r not perfect by any means but I can live with them for sure.
