are the 800s using the same helix as the 1000s now. broke one on my 2012 800 xmr, and went to buy one and it is the same part number as the 1000s now, online on the can am parts catalogue their is a different number on the 800 helix compared to the 1000. but at the store their computer shows that the 800 number is now substituted for the 1000 number and don't make the 800 number anymore?
