Where did you order it from, and how much it costs? if you don't mind.
Ordered from DB Electrical in Knoxville TN for $83.52. Their database did not have a listing for a 2016 Stone II but did show multi applications for Moto Guzzi. Numbers were:0307307110, 14730706, 30730710, 30730711, & 410-40034. I figured that with that many applications I'd take a chance and order it. Good result. A perfect fit!
Their Tel number is 800-753-2242. Also an extensive website at dbelectrical.com.
