i cant find any good rear end pics of em they are all too small or dodgy

Thats a top effort placing those R32 tailights in the coupe....however I reckon they may be a little disproportionate...as in I think the taillights would look a little bigger in relation to the car.
I still reckon its a definate go having the GTR tail lights in the coupe...I love it.

yes i also recon the scale is off aswell.. tom if you seriously wanna see them properly on your car with photo shop, i recommend going for a drive and finding a skyline in a carpark etc. pull up next to it, and get a photo of the two next to each other. then you can get the scale 1:1

and i hope you do this conversion for real, no-one ever has the balls to do somethink diferent (except that blue ute i seen, damn its fine)

it does look a bit strange but it was only a concept idea so i wasnt going for scale, and its not my car

Maybe try R100 RX2 or RX3 tailights
or the C210 japanese round lights

i might just add, because i have a 120y coupe with the removable rear light panel, it would be easier to do this conversion than say with a 1200 coupe with the body, at least if i mucked up i could put the original ones back in, so if any one wants to see it done send the lights and a rear panel this way,
