Hi Again, Kobol.
A couple of things...
First, the hood lock retainers he is talking about (the owner) are different for each the GT/CS, AND Shelby. The GT/CS one is bolted, not welded to what was the hood bumper bracket, mounted on the core support (2). The Shelby one is pop-riveted on (I think), but never welded on.
Second, he has nothing to lose by providing the VIN (not sure what a "V5" is). Something is fishy. Why would he seem irritated at your asking? I noticed another Mustang in the background (yellow one) with another set of LeMans stripes. You should ask this seller: "are the big stripes on the top of the car original"? (trick question--they weren't originally on the CS).
The rear deck stripes are not placed on right--they are too high; but even a few restored CSs have stripe goofs.
This is not the only GT/CS in the UK. I know of two others in the Registry.
I noticed that it also has a bench seat--something very rare. (less than 2%).
Could he provide any photos of the trunk? Can we see the inside of the taillights? We don't want you to have to go to the UK, we can probably figure this out here. The folks here are very knowledgable and vigilant about accuracy.
On another note--here are a couple photos of the Marchal Fog lights. More on that later. First is helping you out here.
Paul.
p.s. if the seller listed this website as a source of information in the EBAY ad, I'm wondering who is now reading this thread that is in the UK, or the seller himself? Perhaps the seller could provide the VIN right here for us, and we can check with Marti. But, in the longrun, JB and others are right--there will be others; maybe pass on this one. Heck, maybe someone here in the States might sell you a real nice one, and ship it over to you (any advice, DAR?).
