Mustang Rear Spoiler Assembly (1969-1970) Installation Instructions

1. To begin installing your new Mustang Rear Spoiler Assembly, use the screws and brackets provided and mount the pedestals to the underside of the new spoiler wing using the screw mounting holes in the spoiler. Make sure that the slotted bracket is on the inside and lines up correctly with the screw hole on the pedestal. The pedestal and slotted mounting bracket should both face the front of the wing, which is the thicker edge. Do not over tighten these screws.

2. Insert the 5/16" mounting bolt and washer from the Mustang Rear Spoiler Pedestal Kit into the side of the pedestal and hand-tighten. Repeat for the other pedestal.

3. Place the Mustang rear spoiler pads on the bottom of each pedestal and carefully measure and place the spoiler on the vehicle. Remove the spoiler, but leave the pedestals in place. Use tape to fasten the gaskets in place on your trunk lid. Recheck your measurements and positioning after taping the gaskets to the vehicle to ensure proper fitment.

4. Holes will be drilled through the outer two holes in each gasket. Do not drill out the center hole, as only two holes per gasket are needed. Check the area where the holes will be drilled for wires or other obstructions, then carefully mark and drill pilot holes.
5. Once pilot holes are drilled, finish drilling out each hole with a 1/4" bit.
6. Screw the threaded rods into the holes in the bottom of each pedestal.
