Does the original MDD base body and the 2.0 share the same size hand internal frame?

I’m assuming they do as theres only one option. Can I put the “normal” hands on the original base body (the one I have)? Will they fit? The hands I took off are large and the ones I want to buy are the smaller size. Just scared the normal ones won’t fit…

Yes, they should fit. Both the wrist joint and the hand parts are the same across the MDD III, f3 and 2.0 base bodies.
