Man... those arms look awesome.
When I was working on my "Z'd" arms I noticed something very interesting. All of the measurements I took showed that the ball joint mount is parallel but not perpendicular to the inner control arm mounts. It seems to be slightly forward of the front/inner control arm mount. Your new ones look to be perpendicular to the inner mounts. This may cause your front wheels to be moved back in the wells a little.
Just an observation... nothing more! Keep up the great work!
