spoiler or no spoiler

Had a 70 duster with the wing, with out it you couldn't judge the distance between the rear of your car and what was behind you because you can't see the trunk lid, after the wing , even with highjackers ,I could see the wing and judge the distance of the rear of the car ,about lift, the company that made the mustang spolier, also made Mopar spoiler, the mounts came with hex screws on both mounts to adjust the angle you wanted. If you decide not to use the spoiler, pm me, I would be interested in buying it. Thanks
