I think the car is beautiful,but are you claiming this to be a "Survivor" or a Restored detailed car?
The gas tank & exhaust have clearly been replaced with new world reconditioned parts,as has the engine compartment.
That's a Y-71 50 month Delco battery in front of it,and not the correct application for the 1970 LS-6 Chevelle.
Buick & Oldsmobiles used it.
Can you release the RPO codes assigned to it as well as more pictures?
