Rubber flaps on fan shroud. Who makes them
 

I am wanting to add some of those rubber flaps (to let extra air flow through while going down the road) to the fan shroud on my car. Who sells these?
Thanks

Do you have any pictures for reference? not sure what you are talkng about

I bet you can get them from Griffin or any large radiator shop.
