i agree with fordy on the lights, the datsun lights are smaller, the lower metal panel on the datsun is taller to accomodate the lights and it lines up wth the datsun boot. it is not a case on the facelift micra that the lights simply hang over the lower metal bit thus covering it up, it has a completely diiffrent lower metal bit, the datsun lights may fit in the facelift micra but there will be a void on the lower section which will equal uglyness
i dont know if this is the case on a pre facelift micra as i havent compared that but its definatly a no go on a facelift
