I think the M tech II bumpers were the same on pre facelift and facelift. I fitted an Mtech II front bumper to my pre facelift coupe without problems. But as Andy said, it will have to be a coupe one.
I got one already painted on ebay for ÂŁ350 and it came with foglights and mesh. Remember though, that if it doesn't come with the actual metal reinforcement bar then you will need new expansion rivets to attach it to your original one. Also, the foglights and brake air ducts off the original bumper will not fit the new one.
