If you don't know the width or backspace of your rims, you might have sevens. 245s will fit on sevens fine, imo. For an early A, the bs will have to be perfect! Yours must be. Cragar SS are famous for a "deep dish" look. It's a very attractive look, but often results in too little backspace. Without knowing what bs his rims have , I'm not willing to say they'll fit, and my experience tells me they probably wont.
