The second generation subframe is also too wide. You will have have to keep the front end up or you will have wheel/tire/fender interferences which after final paint are not good to find out about. Wheel back spacing does not solve the problem. Go to car shows and talk to people who have done the modification before you decide to go that route.
From my personal experience, the IFS kit is the best way to go on the 47-55.1 series trucks.
You can make anything work but it will be a challenge.
