You can swap but you end up with a bunch of dispoasble crap- I.E. stock control arms, trac loc, 28 spline axles- none of which will hold up to 03/04 Cobra power levels, AND you won't want stock GT gears or catback. The only thing you get to use will be the housing and about $500 bucks of Ford parts like brake brackets, ABS sensors, sway bar, etc. It might be worth it but once you swap you've really just begun.
If you buy all good stuff and don't cut any corners it will be north of 3 grand. There is no better start than Postbans blue pill. If you are interested I have a few more part numbers for the Ford stuff and there are a couple things not on his list that you might want. The swap itself is a piece of cake if you have all the right parts.
OR you can beef the IRS and keep the wheel hop, the clunk, the vibe, and the extra 120+ pounds.
