Hi Gary,
The application uses your stock tail shaft. Gearvendors provides a new aluminum cone. I had to cut about 11 inches off my drive shaft and this would be sweet in a street Cobra. In fact they sent everything needed to make the application. If you look at the picture attached to my previous post, you can see the unit adds very little length to the drive train. Send me your email address and I will send you several better pictures of my application.
