OEM Gas Tank Skid install questions

I picked up an OEM gas tank skid at my local junkyard and have questions about installing it. Do you take the plastic gas tank guard off? Do the metal bands hold up the gas tank and then the OEM skid covers the entire assembly? I ask this question beccause the gas tank skid plate I picked up has two indentions that look like they are for the metal bands that hold up the gas tank. The gas tank skid is a complete cover that covers the sides as well as bottom and mounts to the frame rail using the infamous nut strips. I'm up to speed on the nut strips as I made some to mount the receiver hitch when I added it. I'm planning on leaving the metal bands holding up the fuel tank and then covering it all up with the gas tank skid, UNLESS you guys tell me it goes some other way?

Thanks for the help

The skid will fit over the gas tank without removing the plastic protector or straps. Cherokees with a factory skid didn't come with the plastic (at least mine didn't). The cut outs are for clearance.

I cut most of the plastic protector off. The bands stay where they are, just put a jack under the skid and it goes right up. Align the holes with a long punch, philips head screw driver or other similar long pointy object.

The plastic contacts the tank skid on the outside making it difficult to fit properly.
Use a metal snips or knife and trim the about an inch from both sides of the plastic guard. You do not have to remove the plastic to do this.
