Lost reverse, need help finding it. 727

Nothing will fall apart if you back the adjuster all the way out.
If you cant get it out past that lever, the pivot pin will need to be removed.
You can only get the pivot pin out by pulling the tailshaft housing.

You don't have to have the whole trans apart like this, but it shows the pin and where it is.
The part laying right in front of his hands is the band anchor which also goes on the pin with the lever and needs to have the end of the band hooked on it.
