Okay so now we're talking
three different problems now!
The position indicator is one, key not easily releasing from lock cylinder two and floppy shift lever three.
1. Removing cluster involves first removing the trim panel covering it which is easy if familiar with that type work. This is further complicated by the main headlight switch knob removal which can take one of two different paths. If such work seems beyond one's desire to dig into the dash board there's no shame in hiring it out.
2. Ignition key lock cylinder sometimes needs replacing due age and use or some other part inside the steering column needs adjusted/serviced. This can also be related to the floppy shift lever as there are bushings and bolts/screws holding the lever to the column superstructure. For the more adventurous and well endowed tool collection dropping the entire steering column just enough to gain full access to parts under the shroud this is fairly simple. (The column needs lowered only enough for the steering wheel to rest on the seat.)
I'll try finding an exploded drawing of the shift lever etc and mark it up but word of caution---this might take a day or so.
