Geeetech

It is not the right part, there is no room on the inside of the block it goes into, I have the same setup it cannot be threaded in.

Edit: The threads are removed from factory, the throat is fastened with a small screw that locks it in place not threads.

Anyone know where spare nozzle throat to the Pro C can be purchased? all the ones i bought are threaded all the way up like one shown above.
