i recently put a set of tyc elegantes in...and they dont fit the best lol wish they would line up nice or im probably gonna get rid of them
You're gonna have to knock off the locator dowels from the backs of the brackets, slot the bolt holes a little bit, possibly even enlarge the holes in the core support where the adjuster screws go through. Reinstall the lights with the bolts just barely finger-tight, pop the grille on, then shove the lights around until they're square in the grille. Carefully remove the grill so you don't move the lights, and tighten 'em down.
The TYC Elegantes are about the nicest aftermarket lights I ever saw for GMT400's but they are not perfect. I had to do the above to both sets I owned. Then again I've seen OEM lights that sat droopy-eyed in the grille as well.
As far as why they're not made anymore, I'm sure they exited that particular product as demand dropped.
