I, too, could do the fabricating. The ones for the front of a Dodge are a lot of work. Simpler ones, at half the price, just u-bolt to the side of the frame. The Torklift catch the bed tower giving a least twice the distance for twist. And were much easier to install, on my Dodge the fuel tank is tight to the frame on the driver's side, using the blind hole and fish wire. Mind you my kit had only ONE fish wire. It needs two. I had one from a earlier trailer hitch.
On the back, if you have the factory hitch, it's just a matter of a 2 1/2" square tube into the sockets and a couple of 3 1/2" x 1/2" hitch pins.
