Trying to figure out how this kit replaces the redneckery already in place. There would seem to be a very small machine screw missing that would secure the knob (boss?) to the shaft and capture the spring between the knob and the trigger. None shown in any of the IPLs I've checked and there wasn't one in the parts bag either. Also doesn't seem to be any threads in the shaft (at least that I can see).
TIA for any info or enlightenment!
