HELP – Plow installation

I just bought a Quadrax Plow for my 2015 RZR 900 Trail. I’m having a problem putting the mount on. Of course the instructions are fantastic. 🙁

From what I can gather. I have to cut the skid plate to mount the U bolts around the cage frame.

I’m non mechanically inclined. What do I use to cut the skid plate? on the front it is a 1 inch x 1 inch and the back U bolt a 1 inch x 3 inch.

Any help is appreciated.
