Driveshaft question, CV and single U joint?

[Motorcitydak]

I am not quite there yet but I was thinking about my rear drive shaft. My transfer case is from a Cadillac STS and uses a cupped 6 bolt flange to attach to the CV joint driveshaft. The rear axle is a ford 9 inch, I have a few u joint flanges I can use on that. Can I run a driveshaft with a CV on one side and a single U joint on the other? I know that the U joint will change speeds as it rotates but is it really that necessary to address? My truck had a CV joint at the transfer case and a single U joint at the axle but that was for IFS and, well, a truck. This is a different application and obviously I do not want any problems from the driveshaft. This does seem like a rather easy solution to join the two, but that does not mean that it is a good idea.



I showed the transfer case yoke to a machinist who said that he could do something so that I could get a U joint flange on the output. I also know that I could get a flat flange for the 9 inch and have him make a cup of some sort to fit the CV joint into. Should a CV shaft be attached to a live axle tho? Or should I stick to the good ole tried and true U joint setup and have the t case output adapted to hold one? The rear shaft will not be very long, I would guess around 3 feet at the most.
