Can someone decode these numbers for me?

Wow. This is now the highest 1970 Hamtramck VIN I have ever heard of. If you have a photo of the tag can you email it to me please?

Also, does your mylar door sticker show July or August?

The E51 should be B51 - Power Brakes.

YX9 it actually TX9 Black upper door frame paint.
