Just finished mounting the 2 Door style on our 2021 JL Rubicon. We spent about four hours total most of the time was used trying to find the correct mounting holes in the frame and reading the directions. Be sure to understand that the nut plates are specific to driver or passenger side. Also I suggest you thread the bolts into the nut plate then select the bolts that start the easiest for use with that specific nut plate. Once we found the holes being referred to in the instructions the process was pretty easy. Our MOPAR skid pate did need modification which included grinding a 1" deep X 2" long relief area so the SRC supplied bolt head would clear. This potential is mentioned in the instructions. We suggest you start on the passenger side as it is the most difficult. The driver side is like a half hour's work. End result is that your Wrangler will have some very handsome sliders that also assist as a step for getting into the Jeep.
