Measure the u-joint center to center distance from the transmission yoke to the differential yoke. Take that measurement along with the two driveshafts to a driveshaft/driveline shop and they will chop up the two shafts to make one that will work for you. Be sure to place the transmission yoke correctly on the output shaft to allow for normal movement, etc. If you have any detail questions, ask the shop for their advice. Good Luck.
