Wheel dates

[Mr70]

Yep...that particular one looks good.
And just because your other wheel,(I assume it's one you picked up later on based on your wanted ad),is dated 4/13 of 1971,doesn't mean it could never have a come on a 1972 model.
They made hundreds of thousands of these particular wheels,in designated alotments and some probably sat in a bin,waiting to be used up or applied to the following years model.
Although that other one was assembled a year earlier,it's not unheard of to come on a 1972 model like your car.
