Called V Stream, the medium windshield adjusts 18.25-20.5 inches measuring from top of shield to slot for ignition key, tall shield is 20.5-22.75, the shortest shield is 16-18.5
I guess because the tall shield is the widest at 17 inches that's the one I ordered with free shipping, it's supposed to ship UPS today.
If I decide it's to tall I will cut some off but Hopefully it will be fine just the way it comes.
It's going to be interesting to see what kind of effect this tall shield has for me.

Could have saved $18 buying through eBay but since I actually got to talk to someone that actually had all the measurements I wanted I felt it was worth paying the extra $18.
