Mirror blades will fit. However, If the Playfield is not perfectly centered, you would have an issue. You may have to adjust the lockdown bar receiver slightly left or right, depending on which side the Playfield is favoring. The lockdown receiver is where the Playfield locks into. My Playfield favored the right side of the cabinet and mirror blades would not fit. I adjusted the lockdown bar a little to the left and the mirror blades fit great with room to lift the Playfield up and down. Good luck.
