my car is exactly what your asking about.i did mine last summer.i guess the difficulty only lies in how exact you want to be.i did mine with every correct harness,componant,bolt,screw,ect. even the heater case.its alot of work for sure,but worth it when your done.it also depends on YOUR ability.i can help with any questions you have and i still have a boat load of parts seeing as i aquired 2 gn parts cars to do mine.
