Tech Note 1: QU40861 vs QU40894
Both QU40861 and QU40894 Super Duty CV Rear Driveshafts use the same CV components, Tube, and Slip Stub, however the Slip Yoke and rear universal joint can be one of two sizes. QU40894 Has a "Small" size rear universal Joint made to Spicer 1350 Series dimensional specifications. The Cup Diameter is 1-3/16" and the overall width of the universal joint is 3-5/8". QU40861 Comes with a "Medium" size universal joint made to Spicer 1410 Series dimensional specifications. The Cup Diameter is 1-3/16" and the overall width of the universal joint is 4-3/16".

Tech Note 2: Tech Help
Cut your driveshaft tubing to a length that will have the slip yoke at the midpoint of it's travel over the non-splined segment of the stub with the trucks weight on the front axle. Driveshaft assembly can be done by any competent machinist, but best results are usually obtained from dedicated driveshaft specialists who can both finish and balance the finished shaft. For information on driveshaft runout and balance, see my TM3000 Driveshaft and Universal Joint Service Manual or TM3000 Excerpt TSB3510 Vibration, Balance, Angles, Ratings, Run Out, Torque Specs.
