Leathal, I got a few questions regarding your car. I came across a car last year in Minnesota, that was a first gen that looked ALOT like yours. I passed on it as the 350 was in need of a major rebuild, and was looking for a nova instead. It had all the seems filled in the front end, had the rear spoiler seems filled in, and had the split bumper like yours, and had a L-88 hood grafted on the hood, I think it was bondoed on, and had the large rear flaires like yours. I will look at the picture I have of it and see if it has the fender vents. Is there a way I could see a few more pictures of your car, please!
edit:
this is the car I almost bought last year, and seems very similar, but could be a wild goose chase. I could find this car fairly easily.
