How to Install Cervini's Cobra R Rear Spoiler - Unpainted (99-04 All) on your Ford Mustang

Notice: Prefit Before Painting!
Painted or Altered Parts are Non-Refundable.

Important: DO NOT fill in vent holes on underside of wing.
DO NOT blow air into vent hole, it will damage the part.
The flat washers MUST be used in conjunction
with the screws when attaching spoiler.

STEP 1. Open deck lid and remove any trim panels on the underside with your panel puller and/or screwdriver. Remove carpet or floor mat to prevent hot metal shaving burns.

STEP 2. Place the supplied drill guides into mounting holes. (Use a small piece of masking tape to hold them in place if they have a tendency to fall out). Place spoiler on deck lid and align in proper position. Check for proper alignment using tape measure (side to side, front to back). Using masking tape, secure drill guides to deck lid and remove spoiler, lifting straight up and leaving drill guides on deck lid. NOTE: 1999-2004 Mustang owners - some Mustang models do not require drilling.

STEP 3. Slide a 1/16” drill bit or paper clip through the small hole on the drill guide / t-strip stem. Mark the paint surface to locate the center of the hole to be drilled.

STEP 4. Using a 1/8” drill bit, drill hole using the marked spot from step (3). Drill through any inner sheet metal which prevents the bolts from access to the spoiler.

STEP 5. Using a 5/16” drill bit, drill through the 1/8” drilled hole in step (4).

STEP 6. Using a 5/8” hole saw, (only if required) drill an access hole for the screw as noted in step (4).

STEP 7. Coat all raw or bare steel with etching primer. Allow to dry. Place round gaskets on mounting locations. Place spoiler on decklid. Hold in place and open decklid. Then secure with supplied bolts and washers.

STEP 8. When installing aluminum side plates, DO NOT overtighten screws or stripping will occur.
