So I got a cv driveline to put on my Scout and the holes in the front output of the Dana 300 yoke do not line up with the cv driveline holes the yoke is wider than the driveline threads
Take the 1310 yoke (for the spline count) and the driveshaft to a driveline shop and have them provide the proper yoke for that system. For a new one, be prepared to spend $65>$95.
