Did i get ripped off???? pics of my new UCA's

got these parts from the junkyard... didnt notice till last night after i took my old a-arms off, that they look very different.....

did i get ripped off???? is there some step in this conversion that i missed??? these parts are supposedly out of a 74 valiant that i picked out, however i did not oversee them taking the parts off, nor did i see the car after the work was done.
(my car is a 70 duster)

top is the new one, mid is the old one, bottom is the comparison
