Yes that's right apollo, look for the yr cast into the back of them,they will also have little star's cast into were the yr is, if they are ''72 they are very rare and a little more expensive then say one's that are ''74-''76,the ''72 one's have a smaller centre hub (2.5inch ) I think, were as the later one's all had the bigger centre (2.3/4),they also should have globe in AUS cast into the back of them,now, from the front the spoke's should not meet the centre circle evenly, the centre circle is raised and there is no lip for the weight's to mount onto,they are flat were as the fake's have a extra lip so you could mount the weight's and also just check to see that all the number's match up if they are a set.cheer's.
