Brake ducting

I am looking for some sort of a "clamshell" device to aid in the cooling of the front brakes on my Lotus 23. I currently have a ducting hose just pointed at the back of the wheel/disk. Someone mentioned that a clamshell type device similar to that used on a Swift Sports 2000 car might work. Looking to wrap around both sides of the disk to get air to both sides of the disk. Thoughts on where to get the Swift parts that might be modified??
