Well I got my eBay trigger in today and picked up a set screw and tap from the local Menards. Things were going quite well, right up until I broke the tap off in the hole. It's not coming out. So we're on to plan B...gonna try building up some JB weld on the front of the triggerand file it to fit. I ran into some tooling issues (more shopping issues because nobody in this town carries what I need) on another gun project as well...I probably should have just stayed in bed today. At least I've learned from experience my tendency towards ineptitude, so I bought a spare part to mess up rather than the one that came in the gun.
