which key holes are you referring too?
the trunk, you'd have to weld it of course and for the handles, just get 4dr rear handles, easy
just have to paint it thats all
i got doubt about it cuz one of my friend's DA took like forever. problem after another cuz you have to mdify it a little. we gotta go to a mechanic for help too. so basically after installing his, i don't wanna deal the same problem again
