hey guys i have a 94 camaro with a t5 . im gonna rebuild it because it is making the most awful whining noise but i was wondering if it was a world class or not. appreicate the help thanks.

 

There's a seller on ebay named "Thegearbox" who sells almost everything for the T5. His auction explains that a WC starts with the #13-52xxxxx and has fiber sycnros and the non-wc has brass syncros. You can call em so they can better explain.
