I got a kick out of this thread when i saw it. I put 87 Monte Carlo one piece lights in my 89 IROC back in 1994. I wish i had pics to post but theyre packed away since i just moved and the car has been in storage since 1999... But anyhow for those interested you can try this link, http://www.laureneng.com/1806254.html. These guys sell the kit to put one piece composit lights into Camaros, Montes,El Caminos etc. using Chevy Celebrity lights. They used to sell the whole kit including lights ,pigtails and all for around $300 but for some reason im seeing they only sell the mounting kit and you have supply your own lights and wiring for $180. But my buddy bought the full kit from them a couple of years ago for his IROC and it came out real nice.

I put this on because the fiberglass support were falling apart so bad, one of the original lights go ballistic in a hard braking.
(please don't shoot, the bodywork is in progress)
