This looks like a north east Duster by the mid 1980's

I grew up in Pennsylvania and my first car bought in 79 was a 72 Duster. It had L60's on the back and one day I heard this scraping in the rear. Pulled over and noticed a piece of the inside of the wheel well about the size of the small dinner plate rusted off and fell onto the tire. No harm done, I just pulled it out and kept on driving!

Oh, the good old days!!! Its amazing how far we've come in technology since then!!
