42" deck on 410S

[acjohn 0]

I have a 42" deck on a 410. Jacks small engine shows gator mulcher blades for a 42" and a 42" LH. Will these fit? I checked hole sizes and blade length and all match. Also, the shear bolts on the blades. How are they supposed to be installed? Mine had nuts under the spindle flange ground down to clear the spindle housing. Any help would be appreciated. I need to replace the spindle bearings and then i'll be ready to mow!
