I was able to get the housing out. It was extremely frustrating and ended up enlisting my brother to help. Here’s the picture.
I could be mistaken but housing and clips seems to be metal. Clips basically didn’t bend. It some brute force to get it out.
Once we got the first housing out, second one was easier as we can see where to pry. At first, we were prying on two small tabs that rest on metal lip which didn’t help.
Light sockets were in bad shape. I replaced them with late 90’s GM light sockets with modifications to the housings. I’m glad that I didn’t break the housing.
