The key to sanity when reassembling the Series 80 is to make a slave pin to hold together the sear, disconnector and Series-80 thingy when placing them in the frame. Although I suppose one could make a steel slave pin, I find that a Q-tip (paper/cardboard rod, not plastic) is easy to make and easy to work with. Of course, you have to cut to just the right length. The tendency of the paper to fray a bit is good - it helps hold the Series-80 thingy on the stack. Obviously, once you put this whole mess where it belongs, you simply push out the slave pin with the real one. You can make quite a few of these slave pins for a reasonable price (far less than a dime, I think) and keep them in every place you might need one.
