FYI, I currently have a 78 C10 power steering box with my 2005 Vortec 5.3 power steering pump. I'm on my second NAPA made up, leaking, dripping power steering hose. I'm going with the following solution SOON. Contact Pat at Benchworks in Scottsdale Arizona. They have done lots of our 67-72 Trucks with Vortec Engines and have The Best set-up all figured out. They have a later 80s Power Steering Gear Box (Best Ratio) that also uses the late model GM Metric 16 MM o ring (2006 Vortec V8 pump) to 12 MM O ring (steering box) pressure line and the new generation rag joint required. They can UPS you all that stuff at way better prices and in my experiences with them, probably better quality than what you've been talking about here

Bottom line if you ever need a replacement power steering pressure hose in the future, walk into any auto-parts store and get an OEM replacement, no jury-rigging multiple hoses and fittings that can leak.

Just a thought
