Fitting genuine RS4 front bumper?

[Foxmeister]

I know its been asked before but i never took notice then as i didnt need to know, but wots required to fit a genuine RS4 front bumper? I know the sides need shrunk to standard body width, but can i use the bumper bar thats on the A4? Think i need new bumper shocks thou, are these compatible with the standard bumper bar? Does anybody know part numbers?

Cheers for any info.
