I would like to confirm that the Gladiator Rubicon inserts do in fact fit a Sport grille.
I have 3 different grilles and the Willys is stamped as a Sport. The only difference is 2 tabs for the back middle section but there are plenty of other screws and tabs that are direct fit.
I've sold the hard top to a friend. I knew someone would want it.
Bought a billet silver Gladiator grille on ebay, took it apart and painted to match the Jeep.
Added cooling and a little muscle. Not quite as clean as the Willys though.
