First step...modify the trigger pack to semi only.
Remove parts not needed for this build.
Remove the auto notch from the hammer.
Cut out the area where the auto sear goes and weld a plate.
Relocate the pin to hold the sear spring, change out spring with a AR trigger spring.
Next drill a hole and weld in a 1/8" pin to prevent trigger tail from moving into auto position.
The converted trigger pack with welds.
