Is this car F3 amber sherwood poly?

Being that it has been so long since your original post, this may be of little assistance.

I must respectfully disagree with several other responses to this post, but I believe that your correct match is:
1971 DODGE J-4 2259 SASSY GRASS GREEN

For reference see this 1971 Dart with 1971 DODGE F-3 2316 AMBER SHERWOOD POLY:
What color Green?

Clearly, your Dart is not the same...

I promise you that your Dart is NOT 1971 F-3 2316 AMBER SHERWOOD POLY, even judging from the photos.

In 1985 I purchased a 1971 Plymouth GTX 440 from my grandmother who assumed ownership following the passing of my uncle.

It was a beautiful garage stored 100% original solely Michigan vehicle built in Hamtramck, MI with zero rust, and less than 20k miles. It still had beautiful factory original Goodyear Polyglass GT tires, including the full sized spare! Thankfully, I also had all of the original documents (build sheet, window sticker, and manuals).

Unfortunately, during the time that my grandmother had it she created door dings with her daily driver and clipped the right rear wheel well on the garage door side jamb (she had no concerns about protecting its finish).

The color of my 1971 Plymouth GTX 440 Dart was:
1971 PLYMOUTH F-3 2316 AMBER SHERWOOD POLY.
