I have the cnc g-code for the throats. I will share when PM:d, but just for non comercial use. Making just a pair is a days work in a hobby CNC lathe. If I get tens of requests maybe I can check the price for professional machining
The 2445 doesn´t have plastic throats. I don't think the 2441 have them either. I have seen it on 2482 though.
