Yup, what Tech said. Swapping to a different frame requires a lot of extra work that a lot of guys don't consider when starting the project. You'd have to build all new body mounts, radiator support mounts, front sheetmetal mounts, bumper brackets and a bunch of other things. Switching to a MII type front will give you a good ride, upgraded brakes, etc. IMO, the stock frame with boxing plates and upgraded suspension works great.
