Sooo many expert opinions being expressed on the BaT site for this car - incredible. Advertiser for this beautiful '68 is defending every detraction; some of the defenses don't hold up, like the comment about the crossram 'how much does it cost to cast one' ? (paraphrased). I can answer that- about $4-$8K for a reproduction unit complete, depending on who you buy it from. With Winter Foundry casting logo and proper part numbers, including date coded castings.
I can see the answer to the trim tag question - likely original, probably R&R'd during restoration (look at the paint behind it). I know it's a "no-no" to remove one, but a lot of shops will remove it to paint the firewall. Some owner in the past should have told them not to, but hindsight won't catch up with this one. I'm one of the guys mentioned with a documented '68 Z, 06B, dealer paperwork, MSO, complete history stretching back to 1968.
The car is really pretty, despite the detractions. Unfortunately, there are are a few on Facebook that don't agree with the facts presented on the originality of the car, including the seller. Caveat Emptor, as the saying goes -
JMO,
