i put one a column that i believe was from a cherokee into my '91 YJ. I actually bought it thinking it was also from a YJ but the collapsing steering shaft was much much shorter than mine, so i guess its a Cherokee. Everything worked just fine with two exceptions- i had to cut material off the end of the tube near the bearing at the top of the steering shaft to get it to go into the hole in the YJ firewall and now my wipers are either all the way on or all the way off. Im going to try switching the wiper switch from my old column to the new one and see what happens. As far as i learned they are all GM based columns and are fairly interchangeable, just keep your old switches and wiring harness' and you should be fine. Also make sure you get one with a key or your going to have to change out your ignition cylinder.
