I managed to put the box on yesterday to check the wheel offset and the wheelbase, quite the ordeal by yourself.

I'm happy with the way the wheels sit in the fenders so I trued up the centers and welded them in. Wound up with 5.5" of backspacing on the 7.5" rims. It gives me about 3/4" clearance on each side. Hopefully it will be enough with Heim joints on the panhard bar.

I also decided to put in a small notch in the frame. I used some 4" pipe and then I got ridiculous with the reinforcements. A 5/16" plate in the center of the frame over the notch, another on the outside of the frame and then boxed the inside as well. There is a thread on here where someone ran all the numbers and said that with the outside plate and the boxing plate, the frame would be as strong as original so I added one more to the equation just in case. I plan to use it as a truck on occasion.
