Gordon,  I know I got some but can't find them.  They aren't where I thought, now I don't have a clue.  I got them from 
Steinway a long time ago.

Try this.  Use another screw to pull the barrel out of enough lifters and then drill and tap for 4-40 threads. the diameter of a 4-40 screw is only about .110.  Use the top or bottom four. And use a Phillips screw so it will be obvious to the next guy that it is non standard.  I think that will work
