How do you change the battery in a 1987 Corvette?
You'll need to remove the side cover, or at least the three screws connecting it on the front (just inside the wheel well), and the one at the top back (just behind the weather strip for the hood that comes down to the top of the side cover). There's also a screw at the bottom of the cover. This one's a pain to loosen or remove. It can only be accessed from the side. I've just loosened it on mine so the side cover bends out enough to remove the battery. I have never re-tightened that bottom screw and had no trouble with the side cover staying in place.
You have to fully remove the three wheel well torx screws and the top, one in the back of the panel near the door jam by pushing the weather stripping aside
The whole plastic panel then removes like a side cover on a motorcycle
Some people still remove all the cruise control and supports taking hours because they don't know this. I can change my battery in about 5 minutes so you can gauge yourself

5 minutes is a bit optimistic. 5 minutes to figure out what tools to use is more like it. Here's what I used. On the top bolt, use a 10 mm wrench. On the bottom bolt (which can only be seen if you lie down and look between the fender extension and the rocker panel) also use a 10 mm wrench. For the 3 screws on the inner fender, use a torx 30. For the hold down bolt on the battery, use a 13 mm socket, ratchet and extension. For the battery cable leads, use a 9 mm wrench. Finally, if you can start the engine, use the power steering to turn the front wheels so that you can get easier access to the 3 screws on the inner fender.
