If you have a stock zuk case and Stock Zuk axles the CV shaft is perfect for the rear needing generaly zero modification (depending on lift and year shaft you purchace 79-83 being the shortest). Then use a cut down newer IFS Non cv for the front (almost 42 deg of misalignment at the yoke).
Now if you are going Toy axles, you will end up with a compound angle for the shaft with the centered rear. A Double cardon shaft is not meant for this application and should not be used. You will wear out the joint at the pinion side becasue it will spin at a different speed then the other 2. SO I recommend the newer IFS rear non cv (again) cut down. Then do the same for the front. I am not saying that it wont work I have customers using the adapters and cv shafts, What I am saying is it is not 100% correct. Now the front you shoulld never use the cv unless your rig is stretched out severly. IF you install a CV in front you need to turn up the pinion so you dont destroy the shaft and keep vibes down. When you do this you will goof the steering geometry up and the rig will drive for crap, Offroad who cares, on the street it would be a white knuckle ride. Otion 2 turn the knuckles to correct for the steering. SOmetimes easier said then done.
So there you have my take, I have read through the years guys sayng Scott says CV... I never said that for TOY axles. Now you have enough information to atleast make a sound choice on which way you can build it....
hope that helps
