I've had a couple optima red top one in my old truck didn't last at all, 2-3 years another in my '69 bug has been great for 5+ years. I live in a warmish temperate climate and don't really need huge cranking power though.
I'd measure your battery and go to costco and buy the biggest, highest output unit that you can fit, if it doesn't quite fit you can return it easily and get a different one.
