ok the front diff is made of aluminum and it breaks some times
i know that guys have bent the tubes on the steel front D30 and pulled them a part and re tubed them
could you pull a steel D30 housing and press in the alm. D30 tubes?

Though I doubt you could do that, I also imagine it would be tricky to get the rest of the mounting added to the cast center section. I bet it wouldn't be too tough to make a sheet metal style diff work though. A 9" Ford style or similar housing is easy to add brackets, etc. to.
Personally though I can't see investing the big bux into a custom housing and still have the limitations of the front suspension. So now you are talking fabricated/custom housing, custom CV axles, custom IFS suspension, etc. Getting into where it probably would be cheaper and easier to just SFA it and end up with a proven, reliable set up.

I really Would love to see it happen, but afraid it would be even more cost prohibitive than a SFA kit.
