I have a Olympus 50mm f1.4 I am trying to bring back to life.

I was able to bend the filter ring round again. yay!
The aperture is now snappy YAY!

Unfortunately, the focus ring no longer stops and it spits out the lens assembly.
I dont remenber loosing a part.. so what stops the focus ring from over-turning?

Also, the aperture ring has no clicks. (I think someone disasembled it before me) Is there supposed to be a ball or a rod for the clicks? I could probably make a new rod out of wire.
