For my 65 swb with 5.3 4L60e swap I snooped the driveshaft rack at my local wreckers and ended up with a 3 1/2" driveshaft from a 2002 F150 2wd 5.4l 139" wheelbase truck. The front yoke on the shaft matched the 4L60e slip yoke. I cut the rear off and had a weld in yoke put in the back. It was just long enough.
