Airex steering column?

[Rebelfaith]

I’m trying to figure out what steering column would be compatible with my Airex A931. It’s considered an F53 chassis although I don’t know what that means. Recently, I let someone use it and they forgot my tutorial on turning the motorhome off with the switch on the column before disengaging the key. This broke the top top of the steering column off. Tiny piece, but now impossible to start. I have it at a shop in Cedar Rapids for repair but it’s either find a replacement column or basically sign them over a blank check to get parts to repair the damaged one. Can anybody teach me about this and tell me what column will work? It doesn’t have tilt, and the shifter is up toward the center of the dash not on the column itself.
