Please help determine if engine VIN number is legit

[Slant 6 Music]

Hello, hoping people can post me examples of their block VIN number stampings in order to help me determine if a car I’m looking at is legit. It Looks slightly ‘off’ to me so far.
I’m looking at 1971 car
Especially ones built at Hamtramck
Thanks in advance!

Here's a pic of my 71 340

Challenger built in Hamtrack. I owned the car twice. The original and correct color is blue (May build), previous owner repainted orange. Posted both so you can see the numbers better. But it was totally missing 1 number. Numbers matching car I bought from original owner in the 80's. I believe the tranny had a bit of a double hit on a couple numbers.
