OTK Chassis Racer EVX 2008 and brake air duct

Hello, i’m new to this forum.
I have a brake air duct that i would like to add to the chassis but i see that it is longer than the distance between the fixing hole and the brake system itself.
Also, i have only one anchor point to fix it to, would it work if i cut it to measure?
Sholud i add another floating fixing point?
What are your suggestions?

Thanks!
