The problem is that you will need to remove the hub retaining nut in order to verify that.
The instructions show that a regular deep socket will suffice for removing that nut.
It seems that the hub retaining nut of your engine is longer and a deep socket don't work.

Not being sure that the new assembly will work for your engine, I wouldn't cut in place and ruin the hub retaining nut, unless you have a spare.
I don't believe that a cut in place will damage your engine.
The lack of toother is just to make fabrication less expensive; I guess they trust the four holes to increase the grip on one side of a wood propeller, if compressed enough by the central nut.
Before ordering the adapter I made sure that the four-bolt pattern is the same between the DLE 30 and the RCGF 32. And I've got another approach for hollowing out the socket so I'll try that before I cut the prop shaft.
