I got the
Grace 7-Piece SHORT Roll Pin Punch Set to build my second build after doing the first with the "vice grip" method.
I didn't need starters/holders and it was great compared to the vice-grip method. The short punches are great for installing as you have less risk of bending a punch, but they will fall short for removing. their short length only lets you start the removal so you'll need a longer punch to remove the pin the rest of the way.
Quality wise, I'd say yes based on the reviews of other items and they way they look/feel when I was using them. Yes there are cheaper sets but after deliberating I went with the Grace ones. Didn't want to go through stress of screwing something up, especially on an all-vintage build.
Regarding the Pivot pins: There are special tools but I use a needle nose pliers, a knife blade, and a sandwich bag. Use the pliers to get it down, hold it in with the blade, get the pin started over it and slip the blade out. The sandwich bag is insurance in case you goof.
Trigger guard roll pin there is also a special "roll pin pusher" tool that is basically a fancier, more sturdy way of the vice grip method. I just supported the receiver ears, made sure everything was aligned, used oil, and went slowly. Someone in the Retro forums mentioned using shims or a feeler gauge to eliminate any gap between the guard and the "ears" when installing.
