I think the wheels need a centre bore of 58 (not 57) mm -- the factory tend to say 58.1mm, but............ do check!
Inner races stuck on hubs is pretty common. The safest way I've found to do it if either to mask up the top portion of the stub axle and run a bead of MIG down it, quench quickly with water and then from the top down (and wearing safety goggles) bop it with a cold chisel or do the same with a TIG torch (but don't do the bead!).
Basically, this puts a focussed line of heat in the shell, the quenching over-tempers it and makes it brittle, and the cold chisel cracks it along the weld bead. You can then just prise it off with an unloved screwdriver (or repeat on the other side).
Great project!
