I think its the picture. We went off factory mount locations and put them exactly where they needed to be. I squared up the beams on the mount, did the math...drew some lines under the truck for a plum line...and worked with that. then we just put the jig where it would clear everything, like the oil pan, tacked it up, and started building the mounts off the frame.
We used 188 wall 2in, and once he get things a bit more mocked up he is going to make it unbolt able so if we want to we can duplicate it.
