Man, I really appreciate all the help and opinions. As I am sure all of you know, it is kind of a crapshoot asking for help and opinions on internet, but you all have been so helpful and not ONE jackass! (...um... yet)
The VIN#'s 4 and 5 digits are 67, so it was a convertible to start out with.
It is dark now, but I will try to take pictures of the interior tomorrow. If anyone wants close up pictures of anything specific, interior or exterior, let me know, and I will try to take them and post them tomorrow.
About the grille: I really like it too... I actually like it better than the stock '68 grille, but there are some broken parts, and it is a dull grey. I would love to replace it with a new one that is maybe a little more vibrant, but since it isn't a corvette part, I guess I am out of luck. (Unless anyone has any idea where to get one...)
