TMI quarter trim upholstery. It's sure to pass the inspection of even the most discriminating Mustang owner who demands the exact same color, grain, pattern, and details as the originals. They are precut and come in pairs to cover both the driver and passenger side interior quarter trim panels beside the rear seat area. It has thick, expanded vinyl with knitted cross-link backing that looks new longer, holds up to wear, will hold its original shape, and is super-easy to clean.
