The '74/'75 fullsize stuff has much more problem with this than the mid-'72>'73. That is because the shift components in the saginaw steering column are sync'd for a hydramatic division t350/t400 slushbox shift control...in other words...GM shit.
And for the torqueflite, there were many different shift levers on the valve body provided by chrysler for various apps/platforms both in-house and the stuff they supplied to IH and amc (and others).
Once the column components become worn, the control action goes to hell and can't really be "adjusted" any longer.
However, it can be improved by simply starting at the top and working down, eliminating slack at every possible pivot point. That May involve drilling some of the connecting holes oversize and installing some delrin or nylon bushings as found in the bins at any full service hardware department. Those same hardware selection s also will contain bronze/oilite bushings in common size which have a flange or shoulder on 'em.
Just rip all the controls out and be creative in removing slop.
Or...install an aftermarket shift that mounts to the tranny hump and uses a cable, the tranny mounted aftermarket shifter for chrysler apps most likely won't work in the IH truck due to the seat location and placement of the tranny under the hump. The cable shifter allows some flexibility in mounting.
