I mounted the bed and got everything mocked up. I was able to mount the body almost 6.5 inches off the frame. Thats makes plenty of room for the trans tunnel and driveshaft. Since i am bagging it i wanted it to be pretty low but 6.5 put my running boards on the ground when its all the way down. That will give me more room for exhaust and stuff too. here is a pic of the bed on it (not mounted yet).
