Kevin I have a Craftsman scroll saw and mine does both. You better check to see if yours does too. Where the pin type goes in see if you have a screw with a knob. That knob loosens up to install the pinless.
Let me know if you have the same thing. If you do you don’t need anything. I would look in your manual. If you don’t have one you can find the manual online to your model
