As Leeedy said, there is nothing common between the linkage and ignition switch except an electrical park/neutral interlock switch located on the engine side of steering column. That only connects via a wire between the start terminal on ign sw and the starter solenoid.
Since park and reverse are at opposite ends of the shift quadrant doubtful linkage to trans itself is the issue but there are a couple of mechanical things to look for.
There are a couple of safety stops to prevent accidentally going into park or reverse. You need to pull the lever back toward the steering wheel to clear the stops at each end of the shift quadrant. If you are doing that motion and it still won't go then there could be a buildup of dirt and dry hard grease preventing the operation. The entire shift tube inside the column slides when the lever is pulled back. Another poster found that old grease and dirt had hardened in the area of the opening where the tube passes thru the trans linkage lever where it exits the tube and was preventing the tube from moving far enough for the pieces of the interlock to clear each other. Check that the tube is sliding freely as the lever is pulled back.
If that is OK there is a horizontal bellcrank assy almost below where the lever exits the steering column. It changes the vertical movement of the rod from steering column to the horizontal rod to trans. It is mounted between a frame side bracket and a trans side bracket. Make sure the brackets are tight on each side and rubber insulating pads are intact so the entire assy is not trying to twist.
