Expert Reply:
I went out to our warehouse to measure for you and both the # AKEBRK-7-SA and the # 23-106-09 assemblies have a pilot hole dimension of 3.23 inches. Because you mentioned you have a 4 bolt assembly, that narrows down your axle to an AL-KO axle and you will definitely want the brake assembly # 23-106-09 and # 23-105-09. The other assemblies won't accommodate your 4 bolt mounting pattern.
You may also want the mounting bolt # 7-5, lockwasher # 38LW, and nut # 38N. If you don't have an adjustment tool, I recommend the Brake Adjustment Spoon # W80630.
