All tractor implements that take pivoting side ways shock loads just like our factory swing arm, but a magnitude or more greater, all use bushes with grease zerks.
So do I and get not slack between spindle and cradle. Need bearing on soft spindle may wear out sooner than my greased bushes and needles will tend to just rock and roll in limited wear arc, not all the way around like on cam shaft conversion.
I'd highly recommend not to bother welding nuts on the cradle tube, as tube is thin, so distorts easy and thin enough it can't bear must force. Best solution is late Heinz Kulger collars which spread the loads over way greater area of cradle tube. Do not be fooled by a bush wear, as may not be bushes fault but a tweaked swing arm and or cradle.
Do not be fooled that stable swing arm will eliminate danger of entering hinge handling in hot sweepers with a bit of wave to the surface and/or wind gusts.
Bob Patton's rear linkage take a hell of a lot of later loads off the spindle I found.
Tying rear frame bend and rear cradle plates together with the rod at least doubles the load tolerance before elastic distortion occurs.
In Peel I put in the larger OD spindle and had bushes reamed for more bearing area. I had machinist cut two flats in spindle for the two lock bolts to bear on.
Can't imagine a more controlled stable ride, hope you'all get same or better.
