I had to put a front plate on my rx300 2001 also. I got a Toyota mount on Ebay for $25 that said it would install on my rx300 and used two white plastic wall anchors I got at my local hardware store. The anchor face is about the size of a dime and the tail end will fould into the drilled hole. I drilled out two holes in the front bumper lined up with the Toyota mount just large enough for the anchors to be snuged in. I carfully pushed and or taped the anchors into the bumper untill they were almost flush. Be carful not to pop your air bag. Then I used two large, round or pam head, chromed sheet medal scrows to draw the lincense plate and Toyota mount into the bumper. I also put a plastic plat cover over mine which I got from JC Whitney and it came with the screws I needed. It looks like it came with the vehicle.
