Pics of killswitch on 70-76 darts!

I was thinking of doing a push/pull in my 70 Dart. But where? The bumper is in the way. So I think I am just going to use a turn on/off one and ether put it in the rear vlance some where or mabby to hide it behind the LP. When you go to the track all you would have to do is take your rear plate off.
