I tried goin cheap on mine just to end up having them professionally built and balanced at driveline tech in Gresham Oregon. If you wanna go over 20 mph in 4wd and hate vibration I'd just spend the money and have some professional shop build them.
but I did first make my own front driveline using a do it yourself kit like marlins long slip, and then welded a stock ifs cv to the end of that. It's best to clearance the cv for better angle but I didn't know how to do that and never looked into it.
Never tried a cheap rear DL though. I just hate vibration and noises.
In the end I spent about 600-650$ I think on drivelines at driveline tech.
