70 roadrunner air grabber question

Im not sure as to where the spring hooks up under the hood on the vacuum actuater assembly and linkage that operates the air grabber scoop. Could some one possibly post a pic please ?
Thanks!
David

Here's a pic off a 71. The spring goes from the arm off the post to a rail on the actuater frame.

Thank you very much !
Dave
