You don't touch the cab mounts on a traditional, that is correct.
For the bed, you cut a little out of the center on the inside. In this picture you can see the cut line.You just cut out however much you bodydropped the cab, or more if you want to raise the bed floor. And its always a good idea to drop the bed an extra 1/8" to 1/4" so you can shim it to line it up with the cab.
I didn't cover this part because my bed doesn't have that inner structure, so it had to be framed. Which is another way you can do it.Essentially just build a frame where you want the bed floor, then attach the bed to that.
