Rear disc brake conversion

I rheemed out the hole in the caliper bracket a smidgen with a die grinder to allow the axle bearing to pass thru and drilled out the 5th backing plate stud hole on the caliper bracket. I have green bearings on Moser axles but I dont think that matters.... ideally I would have pressed the bearings off the axles , slid the brackets on and repressed bearings back on.
