We snappend 5 or 6 left handed-screw that year, and they are very hard to replace.

Ah, okay. I've never used the left-handed screw, instead deciding to make my own output shaft for the motors. My first run-in with the left-handed screw was at Nationals this year, when 713 experienced a similar problem with backing their motors out and having them disconnect from the drivetrain -- all because the left-handed screw had been bored out.
If anyone is interested, I have a pretty simple part made up in Inventor for the 2003 Drill Motors. We put flats on two sides of the drill output and then threaded my shaft extension on, using two set screws to keep it from unscrewing itself.
Just let me now and I'll toss the part and drawing up on the web.
