They are the same thing Bruce.
There's a few different bumpers from LH-UC:
The plain chrome ones without rubber
The chrome ones with rubber
Body colured ones with rubber
and there's the UC ones which can fit on LX & LH but the front looks wrong if fitted since the UC has a different looking front - rears look fine but the bolts are smaller and in different positions plus the jack points are deleted on the UC bumpers... Hope that helps.
