Boot-Lid Warning-Triangle Holder

Two-piece holder and mounting bracket for storing a reflective warning triangle on the inside of the boot lid. The creator measured and photographed this custom installation on a 1979 300 SD that was built for the US market and therefore did not originally have the bracket; no other model year, body, market or factory-option fitment is inferred. The demonstrated installation uses four plastic rivets plus a roughly #10-24 by 1.5-inch screw, nut and wingnut. Compare the boot-lid pressing and triangle dimensions before printing, use automotive-interior heat-resistant material, keep hardware clear of wiring and the outer skin, and confirm the triangle is retained without obstructing the lid or latch.
