Hello does anyone know exactly where the extension spring, (that's helps pull the clutch fork back) connects to? Thanks

Which model / Year of Subaru?   

If it is an EA82 engined subaru, this post has a Photo that might illuminate your path:

Sorry, 86 brat ea81, thanks

Factory Stock, the clutch return is done by the Hill-Holder cable and spring on 4WDs. FWDs had a return spring on the clutch fork and pitch-stopper bracket.

 

If the H-H has been removed, a throttle return spring can be used, if one doesn't have the correct FWD spring handy.

 

Thank you all for your help!
