"you can use z33 brakes on your s chassis car all that needs to bee done is drill out the caliper mounting holes on your spindles to the bolt size of the z33 calipers and use z33 calipers."
from the following post .....
zerothread/199252 ...which has alot of good info btw on different brake set-ups and brackets required.
Try searching for z33 as well as 350z for more information, and dont make your search too specific in wording, not everyone will post exactly the way you are thinking it should be...with a little time most everything can be found through searching.
