I plan to change the back of my scirocco sportline 2010 to R 2015+, a photo to summarize found on internet

I bought the hatchback from a broken car parts (an original scirocco R color Oryx white) and the 2 rear lights. so, i just need also the rear bumper and the exhaust.
I planned to buy the bumper found anywhere on the net R/R20: (link taken from random website)
Near my home, I have the possibility to get an original Bumper Scirocco R (Oryx white) with sensors, rear view camera, diffusers etc.
But on the sites where they sell the copy of R/R20 it is specified everywhere that it is not compatible for Scirocco R!
My question is: will the original R bumper be compatible with the normal scirocco? what are the differences? especially that on the facelift the bumper R and R-line are identical with the exception of the diffuser
Thank you for your future answers: D
