I can't help you personally, as I am up in Oregon, but there is a good gunsmith outside Roseville in Granite Bay. Don't remember his name, but he is the only one out there I believe. I think there is one up in Redding also.
There is one in Woodland, but he isn't very good.
But, if all you need is a handle, and a threaded one was in position before, I would bet you could enlarge the hole and re-tap it. Even with the cocking indicator. It will just take a bit more disassembly. You can probably find a parts diagram at Gunparts.com. (Numrich Arms)
