Rear you should set up the pinions to be parralel and no need a CV shaft.
Front, it depends....I've run a front Tom Woods shaft for 5 years with no complints. NO CV either, but the splines are wearing after 5 years. Considering the abuse I put it thru, I have no complaints.
first question....are you doing a shackle reversal in front?
If NOT, then you should be able to run perches parallel and not need CV shafts.
If YES, then front should get the cut-turn. IMO, since it's not powered except when in low-lock, it's optional there too...mine is not, but I'm VERY...
check with http://www.highangledriveline.com as well and call Jesse...he will explain whatever you need, customer or not. Great guy, did my rear shaft. Tom Woods did my front, also a great product.
