I know I need to change the driveshaft right. The C6 is longer than the C4 right? If how long of a drive shaft do I need to get. And the bellhousing on the C4 which one do I need to get the large one or the small one. It is that way in Summit and in Jegs. I called them and they told me to call back Monday but I need the car back on the road ASAP. This is my daily driver.
