i could have all the parts for it because i would just by a mustang and give and take as needed. i have heard/seen that the 4.6 is a lot wider then the 5.0 thus would be a lot tighter of a fit. because of ththis doest force you to begin to go into the custom part side of life. i have heard/seen that you need custom steering and headers. this could be a major problem because i don't really have that kind of room in my budget. some help would really acactuallyhange my life here. if i dont need the custom parts what could i do to get around the need of them. any ideas are good ones. unless they are retarded and make no sense thanks to any one .
