If you don't get one with the bike I would look around for a used one.
I have one in my garage also, almost brand new (I doubt it has over 1000 miles on it).
You should be able to get one for around 100-125 used (like new) if you have a little patients.

 

Got everything taken care of. The original contact was text through their website, so that's where all the misunderstanding came from. When I got the guy on the phone he agreed all flstc came with windshields, but the original owner had taken it off and it wasn't with the bike when they got it. I then asked how a used 2017 could only have 194 miles. Maybe someone bought it then died? Turns out it was more like, "Honey, I bought a Harley" "Bullshit, take it back" "Like hell, I'm keeping it" "You're sleeping on the couch from now on" then quickly progressed to include words like Divorce, Child Support, and Alimony. End result, they put a factory quick release windshield on it, detailed it, then sent me a video walk around. So I bought a 2017 flstc with 194 miles on it today.

 

Congrats! You’re gonna love it!

 

I love my '16! I'm shorter and the Street Glide I had was too cumbersome. I've taken a couple of trips on it and it's comfy all day riding! Now the real spending starts for you!! ENJOY!

 

Congrats on the new to you bike, you're going to love her. But just be warned, you bought a starter kit, once you dip into the chrome pool and realize how great she looks with every little piece you add, it can become addicting. Good luck.
