If someone else needs it, go for it; if you don't get anyone to bite Mike, shoot me a PM.
Have 2 Nova chucks now, but they're both G3s - no insert - 1" x 8 TPI threaded and using adapter, because... My Grizzly 1067Z has 1" x 12 TPI thread.
I could throw it in my box, in case I stumble upon a deal on a Nova insert chuck body some day. At least have it, if I ever sell the lathe.
