Well I did it , I did not think I would , heck I even discouraged others from dooing it, but I broke down and did it. I did not want to pull out the barrel on the 65 so I removed the rivets compleatly , even picking out the ring in between the trunion and the barrel. then I pressed the new rivets back in the holes. I used the rivets from 1pats group buy, and I countersunk the holes in the trunion to fit the swell necks. I found the G.B. rivets to be a bit longer so I think they will mushroom over inside just fine. My biggest worry was the rivet getting fatter and not going in all the way but they went in flush and tight. I did the two rear rivets with a bucking bar . I figured "what do I have to loose" rite . I will keep a close eye on them and if I have any question I will drill them out and all I will have lost is 4 rivets. then I can drill and tap for the screws . I will keep you all informed how it goes. I think it will be fine.
