Here's the link within the site that gives you the pad location on the 6s where your VIN could be stamped.

I've never even bother to look at those.....people totally ignore those cars.
If your was damaged by fire, its a good opportunity to convert to a V8...Carbed V8s are cheap, probably cost less than to retore the 6.
You'll enjoy it more when its done and it'll be worth more.
