Hello everyone!
I ran into an issue with my recently purchase Pentax-M 35-70 lens.. The aperture would be move correctly and I couldn't adjust my focal length to beyond 50mm.
I eventually managed to take off the lens mount ring ( I may need more screws now ) and noticed this spring seems to have sheered off

I am asking can I take the same spring from an existing mechanism from say a Pentax-M 50mm f2 and where would this have to be placed? And also can I Potentially the the screws too?
More pictures of the inside
