It is still available and I'm pretty sure it was off of an 86 model.
I think that will be the same as the '81 model column, happy to take it off your hands for $40
Edit: actually I may have misread the diagrams, I think I'll have to double check what column the car has currently. The columns can be swapped but unfortunately the column lock/key barrel assembly isn't compatible between the two and I'm trying to retain the original key.
