1971 duster quarter skins

These skins are made to fit over the original quarter. If you put it on at the door jam after removing the original quarter it moves wheel house back 3 /16" If you put it over the original quarter it closes the door gap. These should be used for patches only . I have these quarters and AMD. I also have installed both. Beware if using as one piece. Leave your original door edge and place the wheel opening where it belongs. Work from the wheel opening out.
