46gmcpu,
Are you referring to the spring that makes the inside door handle stay under tension? The spring is approximately 1 1/2 diameter and attaches on the door strut and the door handle mechanism. I assembled my doors, but may have taken an image.
Yes sir, that's the one. I'm just wondering how exactly it installs. My interior door handles can over-center and don't seem to return properly, so I'm wondering if this would fix it?
