so here's the kicker - you can mount this bracket horizontally OR vertically, and mount a light to the other two mounting holes
super nice quality construction, powder coated gloss black, and comes with necessary hardware in pic! sick!!
for CA size license plates (about 200mm x 100mm or 8" x 4")
slotted plate mounting holes are about 17mm x 7.75mm
mounting bracket / tail light mounting holes are about 8mm
3.5mm thick steel
mounting hole for entire bracket is 20mm ID, so try some big washers if it's going on a shock or axle!
