Although I do not know if I do not see it well, the lever holder bracket is not a bolt fastening on the upper and lower sides, but a method in which a spring pin is press-fitted on the top with only a bottom bolt fastening. There is "There is a spring pin inserted ..." in the manual but this spring pin is too tight to enter. It hurts with a hammer and it finally enters. It is doubtful that such a thing is everywhere, it is better to fix it with a vise or hit it on the anvil. It would be impossible to obviously use bolts to make obedient bolt fixing for trivial cost reduction or using spring pins.
