NB = 99+ Miata
NA = 90-97 Miata
If you can try to get a 92-93 Miata. 90-91's have a small nose crankshaft and after time the nose begins to break because of the design of the bolt and woodruff key. There are ways permanent and temporary ways to fix it but if you want a worry free get a 92-93. The crankshafts were replaced with a big nose.
