Review on DC Sports LPR-100 Universal Front License Plate Tow Hook Relocation Mounting Kit, Black, 12.75 Inch: Secure and Stylish Tow Hook License Plate Holder by Dave Neal

Standard nuts should be replaced with lock nuts. Stainless steel hardware wouldn't hurt either. The mid shaft was too long so I had to cut it down. Installed on a 2006 Mercedes S-65 AMG with parking sensors. I had to install with the shaft in the top right holes and bend the ends of the top number plate down around the mounting plate so I didn't get a constant warning beep. I used the longest offset, medium expansion fit, and medium length threaded shank. I replaced all the bolts/washers/nuts with stainless steel and used all the locknuts. To prevent accidentally loosening the nut on the threaded center shaft, I added a JB weld around the end of the nut and the threads. Time will tell if that works. There is a slight downward rotational force that tends to loosen the nut on a misaligned mount. It doesn't look like it will hold up to an automatic wash and I won't test it.
