some type of fastener such as a bolt and nut the two housing halves 82 and 83 combine to define an arm engaging portion 84 the arm engaging portion 84 is elongated and hollow to receive the pivot end 23 u2033 of an arm of the bail member 22 u2033 the two halves 82 83 also combine at the arm engaging portion 84 to define a pair of peg holes 85 on opposite sides of the portion these peg holes are configured to clamp about a pair of pegs 86 projecting from opposite sides of the pivot end 23 u2033 of the bail member 22 u2033 thus when the two housing halves 82 83 are combined about the pivot end 23 u2033 of the bail member 22 u2033 the pegs 86 are solidly retained within the peg holes 85 to prevent translation and rotation of the bail member arm relative to the arm engaging portion 84 each of the housing halves 82 83 defines a shaft bore 88 projecting therethrough this shaft bore 88 is configured to pivotally receive the shaft 67 of the shaft bracket 65 preferably a pair of shaft bushings 89 are provided at each of the housing halves 82 83 these bushings can reduce the amount of friction between the shaft 67 and the housing 80 of the actuation mechanism as.
