I have a spare front trunk lid that came off of a 1972 parts car. It's in pretty good shape but will need some body work before using it on your car. I don't see any rust concerns. The front has been drilled for a Porsche badge at some point with two peg holes. The front lip will need a little bit of massaging to get it back perfectly straight, but nothing major.
I used it as a test panel for choosing a color, so that is why it's painted in three different colors on the top.
Asking $150 obo. Will ship at your expense but would prefer local pickup.
