I have a cold front from a company called Fia. A quick internet search will turn up a few online retailers. Mine came with a both a winter front and a summer front (bug screen) which mount on the same studs. Fia uses plastic stick-a-stud fasteners which use adhesive to stick to the grille. The advantage here is an easier install and you can remove them without a trace.

The only alternative I found was from Alaska Tent and Tarp. They will also include a summer front if you ask (and pay extra). Their model attaches with metal studs which screw into the grille. The advantage is obviously strength, but you will be drilling holes in your grille.

The AK Tent and Tarp model was going to cost over twice as much as the Fia - but I do believe it is of higher quality.

I think there was someone who retrofitted an older Ford brand to fit, search the forums for more info on that.
