The column attachments (to floor, to dash and surrounding components) are the same on ’76-89 F & M bodies.
The floor attachment is same as J-bodies but believe (could be wrong) the dash attachment is different and as well as the gear shift indicator is at different (J closer to floor, F/M closer to wheel) location.
The electrical connectors changed a number of times over the years.
There is NO OTHER Chrysler vehicle that shares the same floor bracket (FMJ only) or dash attachment (F & M only).
The upper portion of column (the part that sticks out from dash) shares components with most every other Chrysler vehicle (including some trucks) - like tilt mechanism, turn signal switches, etc. as long as you keep tilt columns separate from non-tilt columns. Also keep in mind the differences between the years.
Also the steering wheels will interchange from 1960 something to 1989 – with two exceptions. One is air bag cars have different wheels. Also the diameter of column where it meets the wheel – there are three different diameters that I know of ('69 and down is the third size). Mostly this won’t mater, but if you stick and older wheel in place of one with newer tilt column (which has larger diameter column at wheel) then there is a bit of gap that you can see into the column (is not easy on the eyes – but can work in a pinch).
I have a ’70 woodgrain 3 spoke steering wheel that will fit on my ’77 Volare (non-tilt) just fine – but the chrome/woodgrain looks a bit out of place.
Look at my earlier post
Steering Wheel . Note, my daughter is the one modeling the wheel.
