Just like the title says, hoping for an answer this time 
Somebody must know:(
i’ve heard the bumpers were different but I can’t see how. You could always try…if it doesn’t work, there are more 2 doors than 4 so someone would buy it. Maybe try measuring/comparing 2/4dr bumpers? When looking at body kit sites, most list a 2/4dr rear. I would like to know too, as I am a new 4 door owner. 
Sorry I couldn’t be of more help.
Yeah, there is a difference between the bumper covers, I know that…but I’m just wondering about the support. Thanks for the input:)
Yeah I already did that, and the numbers are different, so I’m guessing there not the same…I emailed them though asking whats different about them
