Power Steering Help

I have had a noisy power steering issue going on due to a leak in the system. Finally got down below and found that it is leaking from one of the steering turn pressure tubes on the rack assembly. Long story short, I need to replace the o-ring for the pressure tube. I have only seen sets that sell all the complete set of rings and gaskets for the entire assembly, it is only just over $30 after shipping. However I would never find the time to replace all the different sealed parts, so I don't want to waste the money on it.

On to my question, anyone know what size or material type is approved/recommended for the o-ring that is high lighted in the picture? Can I just grab this anywhere without having to buy the set and still get the right piece?

 

Don't delete, post the part number. Some may have the same issue and could use it.

Good thinking, let me find it again and I'll post it.
