591-585. Blades have three holes. My blades mount using two bolts to the spindle.
Had a hard time with caster wheel spindles bending and wear. Scut 4x4 in rough terrain and lots of back and forth maneuvering. Changed to 3500# axle bearings, spindles and hubs. At the the time 1/3 of cost of OEM parts. Did require some fabrication and welding. Been trouble free ever since.
I’ll look into getting a set and will post part numbers here when I order them.
