New to the YJ world. Picked up an 87 Rust Bucket real cheap. Chipping away little by little at all the issues. Runs really well. Odometer reads 55k. Who knows. . Eliminating rust on grounds has solved many issues. While dropping oil off at Napa, the RB didn’t want to crank. Checked battery, various terminals, and all accessible connections. Nothing. No idea why, but, I looked at the left side of the steering column. Sure enough, a piece was breaking off. Never seen this piece on any other vehicle. Not sure what the part is. It pulls a piece forward allowing the vehicle to turn over. Any help identifying this part would be awesome. Please see pic. I’m holding the piece that actually fell off. I need to pull the bar on the column by hand to start. Also need to push it in to shut the vehicle off. Am I going to need to pull the steering wheel to replace?
