Ive seen that on occassion, it's two tags stacked on top of one another.
I agree with you oldschool....we can both remember when 71 Cudas were $500 cars, and worth less than 70's.
The trickle down effect will affect all old mopars, so get your relatively cheap A body now, before the rush. I know I've decided to see if i can find a nice 71-2 340 4 speed Duster. Also, watch the 72-74 Roadrunners and Chargers, they are going to jump also.
