You may be able to purchase the Mopar rollup cover from a forum member... that is how I got mine. Just create a post that you want to buy one. I paid $475 for mine, like new!
It should be the same material. His cover has more material so it can fit a light bar. I like the Rain Gear better than the Mopar....Because it can be used (when no doors) with the top on or off. The Mopar rain cover is designed to be used with the top off only.
Concur with Moe_Fugga, check your window sticker. My SPORT has the Customer Preferred Package 24S. It has all those items mentioned (leather steering wheel, remote start, power windows, etc.)
The Overland plastic bumper uses a 4 screw bracket. You should be good, as long as your new steel bumper also uses a 4 screw bracket. I went from the Sport bumper to the Overland bumper, using an adapter bracket from Quadratec. I also reused the wiring from my old bumper.
Agree, maybe you can find some type of light foam/molding to fill the void when in use, install a light bar, or sell/trade it in order to get a cover w/o the light bar option..
