The two aftermarket replacement windshield arms are different:
1. In color - chromed in Aussie and black in Canada..
2. When using the chromed replacement from Australia you can speak and swear in English. Sh#@
3. When using the black replacement you should only swear in French whilst replacing. Merde.
Both providers have been supporters of Spyder riders. Noboot (Aussie) was the first to supply the arm:

Pierre (Canada) has been supplying many parts and accessories and education for Spyder riders for a variety of items.
I buy from both suppliers but I bought the arm from noboot and some electronics from Pierre before he supplied the arms
I believe noboot's arm is polished billet aluminum, not chrome plated metal.
