Does anyone know if you can buy the O-rings for power steering lines/box seperate? The ones that are used where the lines enter the steering box. My lines dont have the O-rings on them, and I cant find the fitting for the return side. I went to auto zone and the guy said I had to buy the whole hose assembly. And the fitting that goes into the box....he said they dont sell that? Havent had time to check elsewhere yet. Does the 'return' side have an o-ring also...or just the fitting itself into the box? Thanks!
