I was cranking my Jayco up to get pics, so I could post it for sale. The back corner popped and wont go up. I've got it propped up now and found what I think to be one of the drive slugs broke. Does anybody know a link to a diagram for how that all works? I've searched, but all I can find is links to cable repairs at the front, nothing really shows how it all goes together in the channel at the back.
