up through the 95 YJ I think. After 86, Its a different column with different plastics/shape and the addition of the light switch and wiper switch on the column, but its the same size and mounts the same. Same turn signal wiring plug, etc. I have YJ half doors on my 83 CJ8 and wanted one key for the whole Jeep. A double sided key/cylinder from a 95YJ swapped right into the 83 column. Its a tad short but still works fine.
