All of the parts are made. Only final fitting is required.
Part on top right is the spacer that will keep the triggers separated. The rectangular piece below the spacer, bolts to the safety and locates on the tails of the triggers. The two small blocks along side of the triggers will bolt to their sides and trip the sear tails.
All in all very simple. I'll take a pic once everything is fitted.
The parts can be fabricated with hand tools. Welding the tails on the triggers may not be necessary, but it was how I thought it would work best.
Enjoy!
