I put the grille in the hole in the bottom of the front bumper. - Toyota Caldina, 2.0L, 2005

I would have done it too ... otherwise the bottom bumper is already pokotsany ...
And what materials did you take ?! describe in more detail, Really useful

Material - mesh - bought for 400r, in my opinion, in the construction market.
The rest: scissors for metal, wire, lighter and scrap materials were in the country.
He heated the tip of the dart with a lighter, made a hole in the bumper in the planned place (burned it) and thus got a hole for fasteners (wire) that holds the mesh around the perimeter of the bumper.
Correspondingly, you bend the mesh by hand to the shape (from the inside) of the bumper.
It is done simply, BUT competently! =)
