63 Dart identification

I'm very close to purchasing a 63 Dart convertible. Thinking of paying 11K. Super clean but does need some work, but totally drivable right now. Some years back it received a 273 V8 with a 904. It still retains the original 7 1/4" rear. It's been repainted, I believe the original color might have been Aqua A-1550.

But can someone help me with the engine block code, fender tag and another tag on the inside drivers door jam.

I'm new here, so be gentle...
