It would have been nice to have an instruction manual (specific to the Teryx) with the mounting plate. You have to blame the designers/makers for that little issue and lack of fore thought.
That same instruction manual should have commented about those 4 shoulder bolts and how life is a bunch easier if you pull the radiator air dam. Although I didn't pull the air dam, I did use a pencil magnet up through the mounting holes to grab the shoulder bolts and guide them into position.
Also, the instructions that did come called for the assembly of the fairlead brackets prior to mounting the winch ... that is a mistake. That fairlead bracket needs to stay loose until ready to put the bumper back on.
