Battery/Alternator Kill Switch location

I have a friend that does some bracket racing in his 73 cuda. He removed the right tail light housing and made a metal cover to replace it. Then put his push kill rod going thru that metal plate. When hes done racing he just takes the plate off and puts the lens back in. Very quick change over. I hope to do something similar on my 66 dart.
Rod

This ^^^ if you're not driving it on the street that's the perfect solution.
