This is a unique way to add some detail to the interior door speakers of your Mustang. this kit includes trim pieces for both sides for the left and right door speaker panels. 3M fasteners pre-applied to the backside of the trim with a protective layer on the face side that is removable after installation. These trim pieces keep the raised portion of your factory panel exposed and then you install the new trim pieces into the recessed portion of the panel. This makes for a great looking combination of factory color with new mirror-chrome trim. These are 12 individual pie shaped trim pieces, 6 for each side. A very unique accessory kit to add that bling to your interior. PLEASE NOTE, THIS TYPE 1 TRIM KIT LOOKS GREAT WHEN YOU COMBINE IT WITH OUR TYPE 2 CENTER SPEAKER GRILLE KIT.(sold separately) Made in USA Laser cut from 1/8" marine grade mirror-chrome acrylic. These trim pieces are a sure way to take your ride to the next level for an affordable price NOTE: If you have applied a cleaner or polish to your interior, you may not be able to remove it with the alcohol swabs provided. You may have to use another product to remove the polish from your interior before installing. You can test a small area with mineral spirits for cleaning before installing, this may possibly remove the polish so that your items will adhere with the tape.  For a more possitive bond, you can remove the tape from the backside and add some small dabs of clear silicone to the back.
