The 6u9000 number is on a tag on the strut tower which matches the number stamped on the firewall.
I have no doubt its a GTR as i used to have a 92 GTR so it has all the right bits.
pumped rear guards , alloy bonnet etc. its white , and has a N1 or Vspec bodykit , front bar is plastic? and it does have 2 doors.
I will double check which plate has what numbers , i agree hcr32 is a gtst number so i will have to look into that and get back to you, i do know that the hcr32 number and the RCR32 model number are on the same plate and its the one with the japanese writing on it.
I will get back to you tomorrow , but thanks everyone for your help.
