The small side body panel on the Corvette C-4 Drivers Side of the Vehicle has to be removed so.... behind the drivers side tire you will remove 3 10 MM  bolts, you will also see a couple of tabs where the hood meets this panel, remove those bolts as well, look under the panel also to see if there are 2 bolts, for I have seen some C-4 models have lower bolts and others will snap in towards the lower portion. Then carefully remove the panel, unbolt the battery negative terminal first, and slide it out from the side. clock and radio presets are the only "reprogramming" you have to do, hypertech power programming will remain current...My best advise is be very careful removing the body side panel, it is very fragile, dont force it, if it does not come right off, you have missed a bolt. Take this opportunity to clean out any residue or matter around the battery support area. Replacing the new battery is just the opposite of removal.
