I was wondering if anyone knew where I could get a replacement tail light cover?

If you are looking for an LE or SE, these are usually easy to find on Ebay of in the junkyard. But if you are looking for the SSE, you'll have a very tough time finding one that's in good used condition. Last year I sent an email to www.gmpartsdirect.com and they gave me 4 different part numbers for the SSE taillights: left inner, left outer, right inner and right outer. They are two-piece assemblies that are glued together. All four pieces were over $300 so I was just going to replace the outers and try not to destroy the inners. I haven't ordered anything yet.

I have no idea where the email is so I'd have to dig it up if you need the part numbers. Or you could email them yourself. If you run across a nice used pair of SSE tails, let me know!

Me too!! I'm going to change some details on mine.
