Stop in for a cup of coffee

Pulled the Park housing...

The lock spring was loose and literally fell out...

But looking at it, trying to figure out how to get it to stay in the appropriate slot. It seems sprung?

Stop washer is a bit bent...

And if it matters the passageway on the side of the housing was plugged with liquid gasket...

Open to good ideas or.even some bad ones on how to get the locking spring to stay in place.
