There were more then 17 of these assembled originally.I believe I have found 30,and are probably more out there if I gave it my full attention.
This is a 1st week of May assembled Chevelle,so that drivers side A.I.R. Ex. tube is the correct design for it's time period.
The earlier production Chevelles,received the "hockeystick" design you speak of,as well as the GH ink stamping on the diverter valve,later built got the GH decal.
If John puts a GH decal on,and loses that Drivers side 1967-69 production #879 Ex. Manifold,for the proper
1970 production,he might just get that BIN price..A Delco
Energizer R-79W Side Terminal Battery would be the icing on this cake.

That being said.
"I wish I had $749,000.00."
