Yes, it looks like a '73 VIN. Most of the important info is on the last line, especially (if I can read it, cuz it's slightly unclear) the "G3B". G = 318. 3 = 1973. B is the plant (Hamtramck) just for your info.
Let me put my 2 cents in here. My E body is the only car I have purchased "finished". It was around the price of the 2 cars you have posted that you are interested in. Mine is a 71, originally a 318 car. I could care less about #'s matching and, couldn't afford all that in an E body anyway. My car was done on a rotisserie and the bottom looks as good as the top side. All the interior was new with leather seats the only thing I had to do inside was a new set of front door panels. The car is literally like new with small things needing addressed as they are never perfect. The motor is a 512 stroker that makes 581hp and 686ft lbs of torque and had around 1000 miles on it when I bought it. If you keep searching you will find the right one at the right price. Not sure what VANDAN is asking for his but, it looks sweet from the pictures.
Late summer of 2019.
