Who's the A body fender tag deciphering guru? Question about a car in the"For Sale" area...

Only real difference on my 70 ac & non ac car, one has holes, the other doesn't. Same panel
I converted a 70 Dart 40 years ago, the cut out for an A/C car leaves incorrect holes from a non A/C firewall.... They could have been welded up... but I see no evidence of that.... And the seller claims original paint... Just seems fishy to me...
