WIth this being an older thread you probably should have started a new one with your questions. It's been a long time since I did this project and I know I had to take the safety aparted at least a couple times, I reviewed the pictures but I don't remember having any problems or if there were special procedures I had to do, so unfortunately, I can't really help you any more than what the pictures show. I made part 20-2047 from a broken drill bit by chucking it in a hand drill & holding it to a grinder.
Here is a pic. I'm guessing I will need to remove the trigger to be able to slide the safety bar forward and the 20-2047 and 20-2048 will be able to be retrieved out of the bottom of 20-2049?
And 20-2049 is brazed with the piece above? And reassembly, the trigger will have to go in last?
1 more question, the top piece(that the 20-2047 and 20-2048 fit into) that fits into 20-2049 is only held in(down) by the pin?
Sorry to be a pain, but just want to take my time and not mess things up
