I think the biggest obsticle will be the fact that chrysler uses a rear steer steering arm. Most aftermarket go with a front steer rack and a front steer spindle and basically starting from scratch on the geometry to work right. The front steer gets everything out of the way for headers and gives the steering linkage a path out of the way. I have been working on a custom setup for my 6.1 hemi to fit and will be designed around a front steer spindle. Making a stock setup with the oddball balljoint-steering arms and female ended lower control arm designed for rear steer to work would be more expensive in the long run, first thing that comes to mind would be a custom rack to keep bumpsteer in check would be big bucks. At least we have the short-long arm setup to work off of .
