What year(s) 300Z exhaust studs/nuts will vit my '93 VE30DE engine? I want to replace all the studs/nuts before they start to break off, as I've heard it's a common problem. They are all fine now (visual inspection)

 

Me again I've also done this. You don't have to specify which year etc... I don't think you could get the crappy studs even if you ask. You will automatically get the upgraded studs. They just happend to be originally for the 300z. I could research the p/n for you but they're at home somewhere. Go to alldata.com and run the tsb for it. Then when talking to the dealer, refer to that tsb when buying the new studs. If that dealer is worth anything, they will know what you are talking about and give you the right ones.
