i need a new battery for the 86 again. went down to see what they had some thing called a exell was all and the interstate. I asked what no Delco and the man said I can get you a delco. so I waited a day from my new battery. it a 6 year 700 cca and 40 bucks cheaper then he exell 650 cca 5 year one. so it does pay to keep it original if you can. I wouldn't have to loose that point .
