Hi: I am an old guy and new member. Have 1987 Mustang GT Mdiaum Shadow Bue Convertible. My son bought it new and I bought it from him 3 years ago. Now has 98,000 original miles. I have installed 3.73 rear, hi-flow cats, underdrive pulleys, sub frame connectors, upgraded brakes, Mac cold air, Misimoto 2 core radiator, Cobra grill insert, and 16 degrees advance timing. Replaced the top with dark blue Sunbrella cloth top from the "Top Guys" which I can put down when it is cold without cracking and it looks great. Don't ever replace your top with vinyl. Currently am moving battery to trunk. Next is 65mm throttle body, catback exhaust and new paint.
