Well, this is a learning experience I guess.
I had to be the crap out of the trigger guard pin. Kept it supported and nothing broke, a few minor nicks on the reciever.
Got the bolt catch pin in easier - oiled it first, and started with the squeeze method first. I'm guessing vice grips would be better than the wrench I am using (angled/resizeable wrench, not sure what you call that).
Front pivot was very easy after some experimentation and an oops. I put in the spring, then for some reason put in the pivot pin, and oops it's not coming back out, had to force it a bit and bent up the spring. (I think I have a spare in a spart parts kit. I hope). Then, I used a pair of needle nose to hold the detent, used the pivot pin to push it all down and it went right in.
Doing the trigger/disconnect thing next - is the little spring that sits vertically inside the trigger, is it slightly larger for the top loop?
