Marlin has this on his rig and I will take some pics of it later.
Here's the pics - note the factory mount just in front of where Marlin has his movable u-bolt mount at. I suppose he need to torch or grind it off since he doesn't use it

See how the u-bolts are able to be positioned anywhere on the frame without it being welded down permanently.
