Hi everyone. I hope this is the right place to post this. I'm trying to help my neighbor out. She has a really clean 1984 Cutlass Supreme Coupe. From the research I've done, there are a couple of dome lights that were available with her model. She has the one with a single map light, like this one:


Over time, the rectangular plastic piece that holds the bulb terminals in place has gotten brittle and cracked, causing the terminals to bend outwards instead of holding the bulb. Is it possible to replace this piece? If not, what about just the mounting plate/lamp terminals, and if so, could someone supply the part numbers to maybe make finding parts easier?

The chrome part of her dome light is in mint condition (even the lens isn't too bad), so I can't justify changing out the entire light unless it's necessary.

Any info or advice would be appreciated! Thank you!
