The shovel on the Nortrac Middle Buster, and the tooth on the Nortrac Subsoiler, do have different dimensions, and would not be interchangeable.

I'm going to confess to not knowing the precise answer to your question, as I've not measured. However, I own a middle buster and a sub soiler, and was interested in a dual purpose one as well.
What I came to understand is that you can either have a really effective single tasker, or a measly multitasker. It SEEMS that if you drive an arm deep enough to be a good subsoiler (12-14") it's so deep that a middle buster just doesn't work, as it cannot flip the soil. Likewise, if you put a subsoiler tooth on the middle buster, you just tear up the surface.
it's a bummer, but as far as I can see, unless you seriously modify one, you're a bit stuck with either-or. Granted it seems like you should be able to put a short enough arm on the sub soiler, but. . . haven't tried it myself.
I guess I'm coming up with "Maybe, but you'd probably want to build or buy a shorter arm to mount it on anyway"
