stevec, I might suggest contacting bobberpros and ask them what bearings fit the stem.
Trailer bearings come in diffent sizes, perhaps the stem was sized to 1 1/16 or 1 1/8 inch.
Either that or take the bearings that don't fit and your stem and see if you can return the ones that don't fit and see if they nhave any that do fit.
