Trying to find any information on my car and 340 engine

i mean, is there any unique work or identifying items on it? stickers on the dash, interesting set up of valve covers/air cleaner, or anything of that nature?

i'm in SoCal and i've seen two green 69 darts today... so some kind of identifiers would help-- besides the not OG california black plate.
Only two unique things.

1. Vinyl top is not the typical Mopar texture, see picture.

2. 340 pie tin on a non mopar air cleaner

3. Loaded with options, but A/C has been removed.

As I said earlier, originally it came with White top and white stripe.
