I'm gonna' head out to get a Deep Socket Wrench to get the strut bar off to install the spacer on Wed. What size are the two deep bolts? 14 or 15mm?

 

deep bolts? They are all the same size

 

Edited: Looks like I'm wrong

 

I believe it's 14mm. Definitely not 15.

 

It depends, mine is 14mm, Jeremy's ( Performance Factory) are 12mm. His is an early 03, mine is a mid year 03. All these cars are different

 

Thanks.

 

i know this thread was 3 years ago.. but a few months ago my supercharger was getting installed and my bolts for my strut bar have gone missing. i have a 2003 350z ... what bolt sizes do i need and are all 4 on each side the same?

 

You need 3 for each side. There's one nut for each side also. They are all the same size. And worry about bumping an old thread. It just goes to show you're using the search feature...
