You are a tad confused. It's not predicated on the housing, it's the suregrip unit itself.
Clutch type suregrip has the thrust buttons. The buttons are easily removed.
Cone type suregrip has a thrust block. In order to remove the thrust block the suregrip unit itself needs to be disassembled.
IF you have the newer Greens then I think the buttons/block can stay. If they are the older ones it needs to come out.
OR as mentioned if the splines on the axle ends are long enough you can just remove a little bit of the axle end.
