This is great info, and the level of detail is much appreciated. I'm willing to give these adapters a shot. My main concern is angularity as well. I don't have the original (and perhaps stronger) Nissan u-joints on my half shafts anymore, and I've heard of these failing w/lowered V8 Z's. Even the JTR manual warns against using greaseable u-joints in a lowered swap, so I feel this might be a better setup.

Great timing on the post - I'm about to tackle the exact same project. 78 280z, 280zxt axles, Eibach springs, etc. I've been debating whether to use the Milkfab adapters or WHP: https://whiteheadperformance.com/product/billet-280zxt-cv-axle-companion-flange-adapters-27-spline-datsun-240z-260z-280z/ Do you (or anyone) know anything about the WHP adapters? My only reservation w/Milkfab is that they list a torque limit of ~400 ft/lbs. Wondering if the WPH adapters are any stronger. They're certainly pricier. How difficult was it to remove the stub axle from the diff? Did you have to pry it out? Also, did you disconnect the LCAs from the spindle pin or from the inside? Good to hear that you're not having binding issues.
