Another Nova help thread

[Gear_Jammer]

We went and looked at the Nova again yesterday. The owner pulled it out so we could get a better look at it. It was a little rougher than I orginally thought, but still a nice original car. All of the numbers checked out, so it's a true number-matching car. We drove it and it drove great. Nice power, comfortable ride and tranny shifted nice and strong. Here are some more pics, a few of which I need y'all's help on.

1. There are 2 holes in the trunk. What in the heck could these have been for?



2. This doesn't look factory. Any idea what/why it's there?



3. Again, this isn't factory. What and why is it here?



4. The owner said he thought this was a clamp for a fire extinguisher. Does that look right?



5. Is this the factory spare?



6. Here are some small rust spots under the rear bumper. How much should I worry about these?
