Steve/ Ron,
All first gen. (67-68-69) V8's had sleeves 3791814 on both hoses. ( not reproduced)
All ' ' ' ' had clamp 3874661 that held both hoses together.
Only 67-68 BB had clip ( P/N not known) that was part of steering box asm.(Steve's picture) but in 69 the clip was a added to all V8's.
Another clip 3953258 was added in 69 to all V8's at the lower engine stand bolt. Could have been added because of the redesigned pump and hose lines.
Steve,
Can you tell me if the steering box clip has ribs on the outer surface? (the part that holds the hose)
I wish I had kept my original 68 RS/SS 396 but sold it to my brother in 75 and under age son took it out and destroyed it. Have been trying to get it back ever since but that is another story.

Bob
