Yes, it can be that picky...you didn't say whether your car was a T, an E or an S...
In '72, all had relatively low compression ratios, designed to run on regular of that year. However, the factory suggested a different plug for each model. I no longer have my books here, since selling my car, but I do recall having better success with Bosch than NGK..
