Many of us are trying to mount our 240Z turn signals into an aftermarket air dam.
You may find that there is not much to hold your turn signals in place (as you can see in the pictures).
Skillard's solution are these 20 gauge stainless steel backing plates. They install on the backside of the air dam and sit over the studs on the turn signal and are secured in place by the nuts on the turn signal studs.
Since these are 20 gauge, they will flex to the contour of the air dam while still adding needed strength and rigidity to secure your turn signals.
Sold as a pair.
