It's definitely doable, but not as easy as it looks. The spot you see in the pictures is a cubby hold in the back of the Porsche 944. It's kinda egg shaped as the outside wall is actually the rear fender. Inside the cubby is a side marker light assembly. The box kinda bends around the side marker and conforms to the hold.Actually, it's all wood. I tried fiberglass but it's a mess to work with.
