66 monaco lower door hinge(door won’t stay open)

Not sure what topic to post this under, please move if necessary

The passenger door on my 66 monaco convertible will not stay open. In the attached pics of the lower hinge you will notice the spring is not attached, it keeps coming unclipped from the lever.
I reattached the spring and it made no difference. I can see that the roller is still in place. Is there anything missing? broken? or adjustments? I looked in the shop manual and don't see anything on this. the only thing i found in the manual is door diagram and is not detailed enough to show the components of the hinge.

thanks

Glen
