Why cant I just cut some off the end if its too long?
If you take the tail housing off and find 4 or five inches of spline then either a groove for an o ring or a solid non splined section, put the yoke on and you'll see it doesn't engage much. It will hang out of the tail housing too much as well.
I don't think it can be made to work properly, but that might just be my opinion.

My output shaft has 5in of spline or more then an Oring. There is no gap between the two. What is an acceptable length the yoke should hang out of the tail housing?
Here is a pic I took the other day of the tailshaft..

8a8mfh is correct. I rebuilt a T-400 using the output shaft from a 4L80, changed to a mechanical speedo gear for use in a 49 chevy truck. The shaft is splined 3.25 inches with an o-ring 1/4 inch further up the shaft. You need to order an old style T-400 slip yoke with 1.88 seal diameter and it will be counterbored (no splines) the first 1.75 inches. This extra machining allows the yoke to slip over the o-ring, reducing the possiblity of leakage when parked. FYI, 1310 u-joints are 3 7/32nds cap to cap with 1.060 cap diameter. 1330 and 1350 are 3 5/8ths cap to cap with either 1.060, 1.125 or 1.188 cap diameter. Larger cap diameters are found on 1350 joints, which don't appear on any production vehicles I've seen.

I've seen vans with output shafts like the picture above, they come from the factory with yokes that have splines to the end. I guess you could cut it off if the yoke was too long, but it could be the output thats too long, or both. I wouldn't cut the output.
Just be sure that when you put the driveshaft in the yoke has at least 1" to move in and out before it bottoms out.

Ok finally got to finsish everything up this weekend. The yoke I posted a link to did work, but I have to cut 3/4in off so it wouls slide in far enough so the u joint would clear the yoke on the rear. But other then that its in a running.

Yeah, its not bottomed out. The driveshaft wouldnt fit past the yoke on the rear without trimming it down. If I had to guess is 3/4-1in away from being bottomed out. I actually wouldve been fine with 1/2in or less but decided to go a little more. I havent had the first issue with it.
