96 Roadmaster power steering question

The hubby is working on a 96 Roadmaster that someone busted the steering column with a hammer. He is going to replace the column, but they always ask with or without variable power steering. Where do we find the sticker and which number shows the option code for the power steering? Thanks so much.

Look at the power steering pump, find where the pressure hose threads into the the pump. If there is an electrical connector to a solenoid where the line threads into the pump, then it's variable assist, if not then it's not.
