i am doin the conversion on my 32 4 door i bought a set of gtr tail lights a gtr bar and coupe boot lid first i found out the boot lid is too wide and to make it fit you would have to start cutting the reinforceing (f#%k that) its easier to modify the sedan bootlid. I also discovered the mounts for the back bar are different a bit of cutting and welding required other than that there shouldnt be too many problems fingers crossed anyway
