Once the T-5 was bolted up to the bellhousing, I put a yoke in it and measured for the correct driveshaft length (center to center on the U-joints with the rear axle at ride height). I then headed for my friendly local salvage yard with a tape measure. A half hour and $10 later I had the shaft I needed. I put new U-joints in it because the shaft had been out in the weather for a while and I didn't feel like waiting for the joints to die after it was on the truck.
