The complete set from mazda includes the boot, 2 doors, glove box, and the ignition barrel, so it could jsut be the barrel not the entire assembly that goes on the steering column, not too sure, but from looking when i saw it last i think it would be jsut the barrel.
oh and jsut advising ppls for a laugh, the original 4ws 89 model steering wheel is 1250 from mazda and yes its still available. lol
