The dimension and type were perfect for the 370z. I ended up having to swap over the guts from the bushing on the z1 arms to make the rod ends work but someone might be able to put together a set by just having a set of inner sleeves made for the rod end bushings.
Fyi it seems like it would totally be possible to convert a set of spl arms the way I did these GKTech, I didnt want to spend $1000+ finding this out if I wasn't sure.

Man, this is very helpful and so close to exactly what I need. I am trying to do the same thing but using the SPL arm. The SPL rod end is a 5/8-18 RH thread, which barnes4wd.com doesn't seem to have. I will email them to see if they can custom make the exact mount with a different thread size.
I know Speedway sells one that has the 5/8-18 thread, but their bushing mounting width is only 1.3" which is too short and the housing ID is only about 1" which is a little small.
Do you happen to know the width of the forged housing without the bushing?
