That is very similar to what the guy I know did. I never liked it becasue the lights were bigger than the blinkers...but I guess it's cool because it's custom. Maybe he did use cavalier lights and i was confused with Caprice? Not sure, I'll will find out when he calls me back.
The setup he did in the older truck looked way better. He actually made the entire grille out of steel grating. Not only bulletproof but it had a cool rat rad look to it.
I'm pretty sure he sold both trucks on ebay...in which case somebody here might have a pic.
