I actually want to mount a license plate on the front of my lx470 and for the life of me I cannot find the screws that should fit. Can anyone please guide me in the direction of the proper screws I should be using? Thanks in advance.

 

You're right, this is an unexpectly non-standard question
I think there are many other solutions besides the standard screws

 

Try 5mm screws...threaded if they go into nuts in the back, or sheet metal screws if you're screwing into plastic. Any hardware store should have what you need. You could also buy them from a dealer, but they'll be more $$$ than your local hardware store.

5mm is the thread diameter, you'll install it with an 8 or 10 mm wrench or socket.
