Thank you all for the warm welcome.
I hadn't considered the spark plug tubes, though that could definitely make sense. I remember seeing a write-up for it, so I'll eventually take a look and see if that's the case.
As for the headlights... I've hit them with 1000 and 2000 grit sandpaper, as well as cut and polish and they still have a yellow hue. It makes me think the yellowing may have gone all of the way through, but it's hard to say. I'll likely try cutting a bit more off in the near future just to really try and diminish it.
Included are a few pics from when I picked her up, flat tire and all.
The windshield was so bad you could hardly see through it. Used some oven cleaner on a microfiber bonnet with the dual action polisher to clean it up.
Last picture here shows the retrofitted HID projector and switchback running light/turn signal shroud, as well as the de-amber. I have clear corners coming in some day (ordered from overseas)
