I never hinted at that linked info (posted above) was the answer,
I just felt that info, was related at least enough to include here in this thread,
I'm still researching your photos as I personally have not seen similar lines on any corvettes I've worked on,
but don't lose hope, there's lots of very knowledgeable and experienced members who are fee to post answers on this web site yet,
and , NO! I'm not ignoring you, I simple have no useful info to include YET!
those might be trans fluid, or maybe power steering fluid coolant lines,or related to the air conditioner heat exchanger,
but they look and are located a bit differently, than on any corvette I've worked on,
, so I'm continuing to look for related info..
Im sure the answers simple and obvious
but I freely admit I don't know everything about every corvette ever made
