Product Description
Ford Mustang 1999-2004 Coupe and Convertible Window Sill Trim WS39351, 1.188" Stainless with Crease
WS39351 is a four-piece polished stainless steel Window Sill Trim Set for the 1999-2004 Ford Mustang, listed for both the 2-door coupe and the convertible. Each piece is 1.188" wide, and the note says the pieces come "with crease".
Four pieces on a two-door
The Mustang has two doors, but the set has four pieces. The record doesn't say how they are arranged, so look at the photos carefully before ordering to see where each piece sits, and label every liner when the set arrives.
The crease
"With crease" means each piece is formed with a crease line, which the photos show. Check that it matches the shape of your sills.
Material
Made in the USA from high-quality 26 gauge 304 stainless steel and polished, the set goes over the existing surface using 3M automotive-grade acrylic foam tape. QAA states the tape holds for a lifetime with no damage to the vehicle's surface.

Preparing the sills
Raise the windows; on the convertible, put the top up as well before you start. Clean the sills with a soft, soapy cloth, wipe with clean water and dry. Inspect the full 1.188" area with a lamp for wax, polish film and old tape, and remove them with a plastic scraper and wax-and-grease remover. Isopropyl alcohol last, just before each piece.
Fitting
Tape each piece in place with its liner on and check that the crease lines up with the sill as in the photos. Then peel the liner from one end, press across the full width, and work along the piece. Fit one door, then the next.
Leave the Mustang unwashed for one day, and clean the stainless with mild soap afterwards.
Before ordering
Look at the photos side by side with your Mustang's sills, paying attention to the crease and to where the four pieces sit. Coupe and convertible are both listed, so either body is covered for 1999-2004. If anything differs on your car, call 877-752-3811 with SKU WS39351 before buying. When the parcel arrives, count four pieces and keep them flat. Because the pieces are creased, store them so nothing presses on the crease line. After fitting, walk around the Mustang from a few steps back.
Matching parts
The two-piece PP39351 pillar set is the only pillar option listed for this Mustang, and no window package is linked. For the lower body, TH39351 and MI39351 are separate jobs from the sills.
Pick a dry day and work in the shade, with the car parked level.

Installation tips: Window Sill Trim Set
- Unpack all 4 pieces and match each one to its position on the vehicle, using the product photos, before fitting any of them.
- Each piece mounts with 3M automotive-grade acrylic foam tape, so clean and dry the mounting surface first; the tape needs paint or trim free of dirt and wax.
- Align the piece and press it firmly into place directly over the existing surface, working along its full length so the tape bonds evenly.
- Fit one piece at a time and compare each with the product photos and the pieces already in place.
These are general tips. Follow any instructions packed with your kit if they differ.
