This is where I found headlight parts for my 2002 Dolphin.
The headlight assembly is from Gmc Safari or Chevy Astro.
You can yse the numbers found on your old light to cross match.
You can also call them as they are very helpful.
I replaced both complete sets on mine.
The easiest way to do them is to remove the grill adn take to complete mounting bracket off.
