As a journeyman Machinist....
My very first thought was the removal of that much of the splines on the end of the driveshaft. It is a rare thing that more than what is needed is used in a mechanical application, and it is always built to a strength factor x % over max stress ratio. Since you mention that some have done this without the shortening of the driveshaft, has anyone ever done an exact measurement from the 1400 rear end face to the max safe length into the U joint splines, and the face of the U Joint? That would seem like the first thing that you would do on a mod like this.
Am I correct in assuming that the shoulder MUST be machined back in order for the VL800/C50 shaft to fit between the 1400 unit and the U joint? Or is that not tampered with either when the mod is done without machining? (That wasn't real clear) I can see that there very well could be enough room into the U joint for the shaft to extend without binding on the rear portion of the joint. But I am guessing that from the mounted face of the 1400/1500 unit and the face of the U joint it must be shortened or it will bind ?
As I am also a lifetime certified all position welder in TIG, MIG, stick, gas, and sub-arc. Cutting and welding a spec tempered driveshaft would be my last choice, and definitely a jig welding application.
I am not trying to stir up anything here, but this seems to leave a lot of questions open as to if the basic measurements were even done.
