If the !4 bolt is a full floater, I'd choose that for sure. That's what I have waiting to go under my wj. And if you have the np242, you can get a sye with a speed output to read your speedo. The 14 bolt has pinion support which only the custom atomic axles have. So that makes them mire desirable than a 60. Thicker axle tubes and I think 35 spline shafts stock as well. You might want to shave the center section. Plus 14 bolts are a dime a dozen so if you ever break a shaft or anything, parts are cheap.the more I think about it the more I want to swap axles, but I want to keep the speedometer (Im not worried about the ABS). Ive heard of a speedo swap, but I dont really know that is. Can anybody tell me what that is? Also I found a 14 bolt and a dana 60 for the rear that I may be able to get for next to nothing. They are both 65" wide. Which one would you choose?
