I beleive the t-5z uses a yellow 7-tooth drive gear like the 83-89 t-5's
Do you have the trans? Peek inside where the speedo gear goes. The drive gear will be color coded.
Black = 6 tooth
Yellow = 7 tooth
Green = 8 tooth
If it's yellow you need a 19 tooth with 3.27's, if it's green you need a 21 tooth
