I tried a search but almost every post focused on the need to change the speedmeter after a gear change and not the part numbers needed. I have a t-5 and going to 3.42's does anyone know the correct part number for the speedometer gear I need?

 

Don't have the part numbers but you can just go to the dealer and ask for a PURPLE 7 tooth Drive Gear and a WHITE 19 tooth Driven Gear for your car.

 

Thanks a lot. That is what I needed to hear. I will keep looking for a number but that should be enough for them to get me what I want.
