I believe both WARN and Xenon look like this around the front market light on ’81-’91. Not sure which flare this but it looks like a Xenon as it does not stick down like a mud flap on the door side of the fender.
Here are Xenon’s on a ’81-’91 Blazer. Being they are shinny black in this picture makes it hard to see the their exact design but they are nice!
You guys are making me gitty to ditch my WARN's and get a set of Xenon's
