I for one hope this is the 68 motion car. But the pictures you are posting are not giving all the detail's, part numbers etc,etc. I was wrong saying the side curtains mount with 5 holes its actually 7. I realize these would have to be removed to mount corvette side pipes and modified to fit the nova rocker. I'm not a corvette guy but do the side pipe covers bolt up from the bottom? Just saying....
Here are rocker curtain holes from my 68.
