I am currently restoring a 1970 Challenger Rt and am having issues trying to find where the spring for the emergency brake goes. In '71 they had provisions for this spring, however I have found that in '70 they do not. It looks like it may go on the cable and that's why every e-brake I have looked at does not have the spring attached. Can anyone help or send any pictures that would show me where this goes? Thank you.
