The Arteb headlight reflectors for the GMT400 models sold in Brazil (and perhaps Argentina?) have been discussed on WWW.GMT400 prior (search this site for "Arteb"). I've been working to acquire a set of these and it appears I'll have two pair coming my way later this month, one pair for my 1998 Suburban and another as a spare. I've learned a bit in the process of finding and acquiring these reflectors, and if there's interest I'll share what I've found. Speak up(!) if you care to hear more, otherwise I'll just let this topic die a natural death. I will say that, if somebody wants a pair of these, the BEST option available is to call your closest friend in Brazil and have them buy and ship them to you using Correios’ “Mercadoria Economica” international service. Pay your friend back using Xoom, Paypal, or similar methods. Unfortunately, I don't have friends in Brazil.
