would like to install 4.8is trim

[snkpkp]

hi

I have a 2004, facelift 4.4i with PDC would like to do the 4.8is side flare and wheel arch and rear bumper trim with exhaust tip. now my question is,,

a) would the lower bumper trim from 4.8is fit my current stock rear bumper?

b) what are the part numbers for the flares which attaches to the rear bumper ? (not the wheel arches which connects with the running board)

i tried finding that on realoem but it only gives the 4 arches part number . Also in the rear bumper section it does not show the extended flare which would compliment the wider rear tires.

thank you
