Jluck, valid point onthe diameter of the commercial B/L, but when I made mine, they were simply cut from the 3x box at a length of 3" to help prevent the kind of "flex" or "walk" that you are describing, along with the blocks being welded to the frame side. I am going to be bracing the frame side of the body mounts, since I don't like th the thinnes of the steel. Shifters were addressed by the cut/extend method, and for the gap between the body/frame, well, I for one, an going to be using some garden edging that I got for $4 for a 25' roll over at the local Big Lots store. Hopefully, the OP will be able to make an informed decision here, with the back&forth that is going here. As for the BJ relocation, I am going to check into your thread, and also find the thread that I saw the relocation in. From me, at least, THANKS for the input Jluck. And I am sorry about the threadjack taking place, but at least this one stayed on topic.
