I'm looking to get a replacement battery for my '65 289 coupe. Does anyone know the dimensions of the original battery for it? Also, do you guys have any recommendations for what kind I should get? The car is basically a mostly original daily driver, so I wanted a battery that was oem size so I can reuse the original hold down clamps. I'd also want a battery that is sealed and maintenance free, like an optima red top. Thanks.
