Try Morgan at forcedmarchfabrication@gmail.com. It’s been awhile since I’ve heard him but I think he’s still working on them. See the sticky thread on VZ58 welding services. He used to tab carriers, do trigger jobs(quite well by what reports were), and do all sorts of repairs and mods. Links in the sticky thread to some of his YouTube videos, and there are lots more he doesn’t link too. Check him out, might be worth a email.
