Sidefolder rear trunnions are easy to install but just takes some time to reprofile the rear part of the receiver, cut for the folder latch and rivet trunnion in place. The lower rivets can be difficult to reach to press but with plinkers riveter set up, piece of cake. It's all easy work.
Did I do that?
Very nice! I wished I had bought one a few years ago when they were more in my price range.
