Bought a new front chin spoiler through ebay. Part was from Lauren Engineering in California. I put the spoiler on my 79 Conquista. I had to cut the wheel well side moldings at the belt line, but that worked quite well. The spoiler mounts with 3 bolts to the front frame, two tab points through the front bumper filler panel, and 4 screws to the wheel openings. I painted the spoiler with acrylic enamel adding flexor before installing and that worked well. Cutting the front filler panel with an exacto knife works well. I removed two screws from the front filler panel mounting using a 9/32 socket and put screws in from the back side that hold the molded in tabs of the spoiler. I will send photos of the installation if anyone is interested.
