That there is an awesome photo of the "then and now" '69 ZL-1.
I have some original engineering sheets for the Estes 1968 Corvette ZL-1 Test Car (#88071).
I think the topic of the pilot line 1963 Corvette build came up some time ago. I found my folder with all the pics. I thought this photo was the most interesting. I tried to zoom in but it's very hard to read. It's basically an instruction sheet on the assembly of the rear body structure.
