71 Duster 340 Fender Tag

I'm a new member on board and new to the Mopar community. I recently purchased a restored 71 Duster 340. I received docs with the car, including breakdown of tag codes, but I wanted to get expert opinion on the options listed. I also wanted to ask about options on car, which don't appear on the tag. It reads top to bottom:

R11 V24 V6X V8X EN2
L31 M21 M25 N41 N42
G15 G37 J25 J45 J81 L25
V1X U A01 A04 C16 C55
GW3 L6X9 5X8 420 (I believe is build date in 1971)

Car has power steering and power front brakes, but I don't see codes on tag. It was presented as factory equipment.

thanks, any help is greatly appreciated.
