I didn't, If anyone is looking at that 1.5" gap, they are to close to my ride.
But if someone wanted to cover the gap.
This will work very well, with alittle cutting and gluing.
That is Kydex, the same material Pistol holsters are made from these days. Its extremely durable and stiff.
Cut sheet in half.
cut the center hole fog light lense wil protrude through. place the half sheet behind fog light hole.
Use a pencil to trace around the fog light hole onto the sheet.
Trim sheet down to 2" from the trace line.
Cut V's into the edges pointing towards the traced line.
Use razor knife to score a line across from each V point to its neigbor V point. Do not go inside the Trace line.
Use a lighter to warm the kydex on opposite side of score line.
Fold kydex back to a 90*
let cool.
Do this all the way around
Clean rear of valance around fog light hole with soap and water then 91% isoproply alcohol.
Scuff the edges arounf the fog light hole with 90gritt paper as well as the iside of the Kydex "figers" you made.
Apply JBweld to both scruffed surfaces.
Slide kydex onto valance.
Let hardned over night.
Bolt in fog light.
No more gap..
