Thinking about cutting a slot on the inside of the bottom tube so I can insert the front edge of some 4mm Coroplast. This will provide a bottom to the adjustable air dam and also become an automatic return spring fer the air dam. Obviously the flutes will have to go front/back instead of side to side to provide the return force. It will be same shape as my extended air dam belly pan...just a little bit longer to provide an edge to the adjustable air dam.
Since I didn't plan on doing this mod away from home...I need to source some Coroplast locally. Might have to buy some instead of finding it fer free...oh well.
Looks like
NuLine Signs will be my source...
