This is an 82-92 Firebird fiberglass WS6 hood. This hood is specially designed to match the lines of the car. The scoop matches the flow of the fenders and the scoop inlet angle matches the lines of the front bumper so it looks like it belongs on the car. The scoop is 3-inch at the windshield for visibility but 5-inch at the center. This is a bolt on hood that attaches using the original factory latch and hinges. (Note: This item ships truck freight with shipping cost due at the time of delivery. Please contact us for a shipping price. Many of our fiberglass parts are currently made to order.
