USCT inboard kit question

Man, that looks awesome! Do those springs have enough droop in them to pull the wheels/tires without having to unbolt either the front or rear spring hanger? That's the issue I'm running into with my 66 with the 315/60s.
Me too!, it would probably be down another 1.5 inches if I had the room in the wheel tub. Unfortunately I don't have any pics of the install but I moved my rear end back 1.5 inches which moved the leave springs mounting points back. To compensate we welded some small plates to level the frame rails out where it ties into the back then just set the sliders up according to the instructions on front to back placement. I made sure the sliders were inline to each spring and not off side to side and welded them in. It was pretty simple really and given the results I wouldn't hesitate to do it on any mopar build.
