join the club ive been trying to find one of these too.....
i did some reasearch a while back and couldent find anything regarding these billet type grills.according to a mate there every where in japan at dismantlers etc so if you know anyone in japan get them to keep their eyes open and if you find more than one let me know cos im keen too.
ive even tried hitting people up in the street seeing if they wana swap for my oem type but had no joy doin that either
I've made up stuff like this before, for the hotrod crowd
These ones are pretty simple, just made from square section or flat's bent over a former and then welded to a frame in behind, only thing is they take ALOT of time if you do it freehand, make a jig to set your spacings it'll save you alot of time and make for even spacings
