The '80-83 J-body (Cordoba, Mirada and Imperial) are all a direct fit - with exception of electrical connectors which change every couple of years or so.
Of the J-body steering columns, there are these options (which every version might not exist):
Non-Tilt column shift (automatic)
Non-Tilt console shaft (automatic)
Non-Tilt console shift (manual)
Tilt column shift (automatic)
Tilt console shaft (automatic)
Tilt console shift (manual)
Manual steering columns are longer than P/Steering cars are - but I don't think I've seen a manual steering J-body before.
With that said, the F and M-body steering columns (all six versions) are almost the same as above. The difference is the J-body column to dash attachment point is closer to the firewall than F/M bodies are (by four inches . . . maybe). A person might be able to make an bracket to adapt a F/M column to a J-body but that will require some work
The '79-81 R-body column looks similar to J-body, but overall is a lot longer and uses a different means of attachment to the firewall.
The upper part (the part that is exposed rearward of dash) shares parts with ALL Chrysler products made '80-90 - with exception of L-body cars (Omni/Horizon), pickups and vans. The pickups went to this version later on ('84 maybe).
