How do I install a sound mod for a car that isnt made for it?

[matsl]

Hi guys, I've been trying to install a blown diffuser mod for SimDream's f1 2009 cars.
The problem is, it's made for f1 2010 and I can't get it to work.
The RedBull also has 2 .bank files and the GUIDs also says it has 2. Any help?
