I couldn't be happier that vinyl upholstery was available and so reasonably priced for '87-89 Mustang GT seats. I have some of these in my 1979 Mercury Zephyr and they match the rear seat perfectly. Even the stitch pattern is right! If it hadn't been for this option, I would have had to have my rear seat custom-upholstered at great cost if I wanted it to match my front seats. And the upholstery fits as well as the factory covers I took off. Thanks TMI and CJ Pony!
