What exactly is that thing? I've seen photos of K4s with and without them.
It's basically power lines for the lamps. There are markers on the left and right, and the center one is a backup light. There are different configurations possibly for freight vs. passenger, but this is unconfirmed.
Wow, you're modding already? And the new car smell hasn't even worn off yet. Looks really good, are you stripping or painting over?
You bet. Remember when I got those sweet GHQ reefers and weathered the hell out of them?
