I have a 05 AT Sedan G35 with the 3.3vlsd. I want to swap for a 3.5VLSD found in G35 and 350z 6spd (non base model). Most junk yards dont know if it has VLSD or not. Some dont even know if the car was AT or MT. So I need to find out if there is an ID number on the pumpkin (differential carrier)? For example, nissan use to put orange VLSD stickers on some 240sx cars. Is there a R200V stamp on the outer case?
