So I recently misjudged the height of my liftgate vs the trim on my garage and tried to back out. The garage took more damage than the Volt did, but I cracked the plastic “lens” that goes over the third brake light. I looked at the part list on https://www.gmwholesaledirect.com/a...l4-electric-gas-engine/body-cat/liftgate-scat but part #12, the one I need, isn’t even named. Anyone have any idea what the official name for this is? I’ve had little luck googling because I don’t know what it’s called. I’m not even sure it’s worth replacing, but the crack is one of those that makes the plastic semi-opaque and is directly over the lights (of course).
