Hi I’m in the middle of replacing my battery on my 350z and there was a leak and a ton of corrosion on the plate the battery sits on. I wanted to remove it and clean it but I can’t seem to get it out. I removed two bolts toward the front of the vehicle but the plate still won’t come out. I can’t find anymore bolts or fasteners because the rest of the plate is covered in acid and corrosion. Any ideas?
