Hi there,Was wondering what battery i need for my pickup:Specs:1979 Ford f-250 4x4351 Mod.200 amp alternatorruns a winch, stereo, stereo amp, KC highl

Here are the options from Optima, but with all those extras, I would bump up to the D34 or D31A size if you have or can make room for a bit bigger battery...

Here is a link , you can compare sizes, etc ... just scroll down the page a little to the Yellow top batteries...
