4.8is bumper replacement instead of spoiler

[patrickkc]

I know this topic has been covered a billion times on the forum, but I can't seem to find anybody replacing their entire bumper. Most of the threads are people with the regular 3.0/4.4 bumper and adding on the rear spoiler instead.

I looked on ebay, and there is 1 4.8is rear bumper and 1 4.6is rear bumper. I was wondering if there is any difference between them? Also, I had realized that the 4.8is rear bumpers come standard already with the wheel arches, so if I were to purchase the 4.8is bumper I would also need to buy some sort of rear wheel arches to complete the rear portion?

Once again, I'm buying the whole rear bumper. Not the just rear spoiler. I would assume the 4.8is bumper would fit on a 3.0 as well?

Any help would be very much appreciated!
