Hi! I'm from Spain. I have a Camaro z28 year 2000 and I need to replace my battery. I need to know the minimal ccc, Ah that i need. So the stock specifications for the fine work. I CAN'T TO BUY optima batteries because I'm from Spain. There are only varta, bosch, batteries here.Finally I would need the biggest battery size that fit in the tray box battery. Thank you.Sergio
