If you are replacing a front plate, then you can just re-use your existing screws. If not, then you will need to purchase some hardware and attach the plate and frame to the vehicle using one of the methods described below.
If you have holes in your bumper, any of the screw kits are they way to go. If you don't have holes in your bumper, you will either have to drill them and get the screw kit or just go with one of the 3M dual lock kits.
Import Vs. Domestic Locking Screws
Import screw kits use metric size screws and are meant for foreign cars such as Audi, BMW, Mercedes and VW.
Domestic screw kits use standard size screws and are meant for US cars such as Chevy, Ford and Dodge.
3M Dual Lock
The Dual Lock kits are adhesive on one side and velcro on the other. You mount one side to your bumper, one side to the frame and mate the two together. If you remove the 3M kit in the future, it will not harm your bumper or paint. We give you five mating pairs--which is more than enough to secure the plate and frame to the bumper. If you have a black bumper, get the black 3M kit. Otherwise, get the clear kit. And while the kits will hold up to driving at high speeds, they don't hold up well to thieves or car washes.
