Battery Shutoff switch location question

i would throw in a little caution here with rod type linkage. i have seen it happen. got a call from a friend that had that on his street/strip car. if you use that type, make a detent in the rods. as the linkage wears, it my become loose to where it my slide like stuff does in the bed when you take off. sure it will probably be some time before it is sloppy. story on friend. he hammered it to get on to highway and his was so loose, it caused the rod to slide to off. he had everything in the car power. door opening solenoids, windows, etc, etc. he could not open the doors, roll windows down. called and said he needed help. when help arrived, all that needed done was flip rod to power.
