Hey Man...
Here is a picture of my truck with a stock crossmember and bagged. I have aftermarket Choppin Block arms, which is equal to cupping your stock arms. But it will lay the crossmember on the ground. Make sure to change out your header to mid length, cause full length will hit first.
In the rear, it is all under the bed setup. I will try and take more pictures so you get a better idea. The fender isn't fully on because I haven't cut it to clearance for tires yet.
