Part numbers needed

[ctgilles]

Hi,

I went to Munich last week and got the 239 wheels in 21", they're massive But now I need the flares on both front and back arches because the wheels are sticking a bit out and technically that's not allowed in Belgium.

I just need the pastic ones (not the primed ones) like they come with the 20" Y-spokes. Already went to the dealer but they are retarded, so I need the flares that stick out a few centimeters. Like here:http://www.xoutpost.com/595057-post22.html

I found on RealOEM.com:

Retrofit kit, wheel arch extensions 21" 1 51710007390 See EBA 0429855
Is this correct?
