Speedometer Driven Gear

So I need some advice. I've got a 91' Bronco, 351w V8, E4OD, BW1356 w/7tooth yellow drive gear, 8.8" running 3:55open.

Factory tire size is 235/75r15. The previous owner upped the tires to 31x10.5r15 and the Speedometer Driven Gear was never changed, causing a speedo discrepancy and because it's the E4OD it shifts into OD rolling too slow and bogs down. Now I'm upping to 33x12.5r15 because the 31's that have been on it are 14 years old, out of round, and all I have right now is the set of 33's off my big rig until I can get a second set of 33's. I need to change the Driven Gear to a 16tooth and as far as my research has led me to believe I need 16tooth Blue D0AZ-A for the auto transmission but all I can find is the 16tooth Wine C0DZ-A which is supposed to be for the manual transmissions. What is the difference if any? Can I use the Wine 16tooth? Because if it bogs right now into OD then I can assume it'll have a really hard time dealing with the extra rolling mass of 33's
