Found a 70 Coronet R/T ???

Well I went back to the car today and looked it over again. My digital camera died when I attempted the first picture, which drew a string of colorful words from me! A pictures worth a thousand words, so having no batteries really pissed me off. However this small photo was taken with my sons phone and is of the fender tag. It seems to say the following;
E44 D31 820 S77
?1 1X T?
A31 072123 F?223

The "?" means I wasnt sure about that digit. The dash had two rivets but no VIN tag attached, but it did not appear that the old one had been removed, (no scratches or damage in that area). One small tag was found in the driver door jam, by the upper door hinge. It was heavily painted over but the number appeared to match what was on the insurance paper work listed below.

Looking in the ash tray I found the current insurance slip and they listed the vehicles Identification Number as, T0102123, a 1970 Dodge Coronet. The glove box door said Coronet 440.

The hood was steel, and if I remember correctly, was painted black, top and bottom. Speedometer was a 200KPH one and appeared in good shape.

The clutch pedal did nothing and was positioned against the firewall. Shifter was a B&M setup.

I had a 69 Coronet 440, 4-door with a 318, while stationed at Fort Stewart, GA back in 93-95, so I am somewhat familiar with these cars.

Hope this info helps figure out what this car is, not that I'm looking to buy it.
