Porterbuilt front and rear with a 4l80e?

[Redxbob]

Ok i have a question and i cant seem to find a straight up answer, i tried calling porterbuilt but havent gotten a answer on the other end of the phone for over a week.
Will a 4l80e hang too low below the frame rails with the pb extreme dropmembers? What have people done to make this work with a 6.0? Im trying to make the right decision with this truck and would prefer a 4l80e over the 60e but unsure of the fitment issues. I have a "big hump" tunnel. Ive searched the forums and know its been done but didnt find much info about how it fit and if it hung lower than the 60e
