Speedo Assembly

You should be able to swap the speedo drives between the two transmissions. Just be sure to swap the gear from the speedo drive in your car to the drive you swap into the car to keep the speedometer reading correctly. You'll also need to pay attention to how the drive is inserted into the transmission. It has marks on it and can be rotated in the trans to account for different diameters of drive gears. Pay attention to what you're doing & you shouldn't have any problems. Jack up the rear of the car so you don't have as much trans fluid run out of the car when you swap the drives.
