Thanks. Rob that doesn't have one with side posts which is my current setup.

MFW-has to be the normal group size as factory. Meaning I can't put a tractor battery that weighs 120 pounds in the car. But really just needs to be any normal size/weight battery so the optima's work. Autozone buys batterys now for like $10 so don't have to worry about disposal fees.
Car has a volt meter, bulb, and I guess resistor but need to check-it charges just fine.

I'm getting a group 75 from Battery's Plus that has side terminals-it's a AGM battery that is a rebadged Deka Intimidator so made in USA.
