Yes, you will have to source the correct type.
I have two box blades and they have a different way of pinning the ripper shanks.
Make sure you buy the heaviest box blade you can find. Weight is the deal with any ground engaging implements.
Here's a photo of one of my box blades and you can see the ripper shanks are notched in the back and the pin kinda just wedges in the slot.
My other one is a John Deere and the shanks have holes drilled in them, the pins secure through the holes and require a hairpin clip on the pin, which is the type that Tractor Supply carries and more common.
