Wrong but i saw that just a minute ago whilts looking and it dont look half bad except the remaining gaps need to be smoothed !
Hmm, i am intrigued as to what your plan is
The only reason i said what i said, was because i considered (for about two n a half minutes

) attempting this with my genuine R32 rear bumper

Then i thought it was too much of a gamble on a genuine bumper to piss about with, also, i like the standard r32 rear with my Milltek R32 system

Back to your original request; if it stops pissing it down with rain, i'll go measure up the bumper (which should be on my car, but is cutting a lonely figure in the back garden)
