This mounting plate bolts inside the engine bay and uses factory bolt hole location so no need to drill holes.
It's CNC cut to precise dimensions and fits  nicely over drivers side fender well.
Multiple holes are cut for different options of placement for the ARB compressor.
You can also mount other accessories like  after market fusible link box as seen in the photos.
It's made from 12G steel and is formed as one piece.
 
NOTE, you will need to paint or powder coat the mounting plate. Comes uncoated so you can paint it your choice of color.
