Well, i guess the most current photo posted by Ed confirms this. This is the version I will now pursue. You are dead-on about your ebay comment; everything was off of a "Camaro" and was, in addition, of course, an "SS".
Regarding the hose sleeves; the material is similar to rubber plumbers pipe insulation, I have seen it on period and later other GM models As I remember, it was semi-bonded to the hoses to keep the purpose of its location. smooth outer surface and the inner core a bit more textured.
Thanks for all the replies everyone.
