Help With Possible LS6 Chevelle

[XXXGoldL34M20]

That is an LS6 only rear end which is a good thing but not convincing enough to say the car is actually a real LS6 car without the rest of the drive train missing and no documents.

Does the car have a gauge package? i know you mentioned the interior is gone but thought i ask if the gauges survived?

Looking back at the link i posted, i spot a picture that clearly shows your car came with a four speed bench seat because of the unique shifter hump i see.
