Try giving Nissan Middlehurst a call. Ask for Parts
I bought a set of 'Nismo' marked ones from them. Also if you get the Chassis number from a V-SPEC II (it came with clear front bumper indicators and side repeaters) you could always order these based on the chassis number since they will be even cheaper again.
I cannot remember the exact price now but I know I paid a LOT less than 185 from them when I fitted them (originally on my R34 GT-T).
Since upgrading to the R34 GT-R V-Spec I haven't changed anything (I've only owned my new car a couple of days so far!!!) but I shall ask Middlehurst next weekend and see what they say...
