Look, dude, obviously you have no idea what you're talking about.
While you may be "pretty sure" that it's custom chrome plated, you're dead wrong.
You can buy chrome valences (in a variety of styles for both 2wd and 4wd bumpers) from retailers such as FBI Minis. Since minitruckers of all stripes do the conversions (I've seen it on Chevys, Mazdas and Nissans) I thought there might be someone kicking around here who has one/knows of one for sale OR knows where I can get a chrome valence locally (I'll order out of Cali if I have to, but I'd rather not).
Now please stop derailing this thread. If you don't have a chrome valence for sale, know anyone who has one for sale or know where I can buy one brand new in Canada, don't bother replying.
