Okay I know I am a girl and this will seem like a silly question but please don't laugh at me.
I am wanting to put in a second battery and I have gone and got a battery tray - can I screw this to the car with standard screws or do I need special screws?
Also I am looking at the Redarc isolator from all I have read it is the best - Is this easy for me to install or should I just go to an auto elect??
