Instatiating interactive cloth,get colliders?

Hi i am doing a game where i am running a chopper. I want to be abel to drop out a rope from the copper and be abel to get one side of the rope to get stuck to my chopper and the other side to be stuck to what ever first rigid body i hit.

Iam using an interactive cloth as rope and have made it a prefab but it seems can’t
save the collides in prefab and i also need to make a script that finds the first gameobject that is a rigid body and is collided with my interactive cloth.

Any ideeas how to make this ?
this is my code so far. The boolean are not working atm but that i think i can fix.

var Rope : Transform;
public var RopeOut : boolean = false;


function GetRope()
{

		var Rope = Instantiate(Rope, transform.position, transform.rotation);


}


function Update ()
 {

		if(Input.GetKey(KeyCode.E))
                {
		
		if(RopeOut == false){
		
		print("Trying to get out the rope");
		var RopeOut = true;
		GetRope();
}
		
		}
		
		

}

could not find any good way for this so i made the cloth an child of an other object that i instantiated.
