Hey sup all, wasnted to know if you guys new what lug nut size the 73 nova had or wheel size cuz my cousin has a set of mags of his grand national and he stays in arizona but he would ship them to me but might they fit???????

I think its 4 3/4 inch spacing. My nova wheels fit my S10 and vice versa. The only thing you might have a concern with is backspacing. (the wheels might stick out past the fenders) but I doubt it. Get the rims. YOu can always sell them if they dont fit.
