To fit your flat face 40s steels, you should use 40-48 hubs and drums, which will fit on your axle. If you want to retain those drums, you should cut or grind down the 5 raised nubs to give a flat surface for the wheel to bolt against. The studs will be long enough - but only just.

Gotcha, yes I do have an emergency brake. I'll try to find some hubs and see what they will cost to replace. Might be worth just shaving the nubs down and saving the money.
