Thanks guys, keep the ideas and theories coming. Plenty to think about and I appreciate the input

Don, couple other things to consider about 3-link type suspensions in a unibody chassis...

The links always exert force along their own axis (push or pull) so the upper link must be adequately braced front to rear. Many of the versions out there punch through the floor or add a mount above the tunnel. This area was never designed to carry that sort of load. The rear floor behind the seat is basically a big, mostly flat, panel...

Also, any sort of side angle built into the upper link will cause binding in the rear suspension. As the upper link goes into tension under power, it tries to straighten it's own load path, which pulls the housing sideways and binds the lateral locator. This was a lesson hard learned for me, as I chased this problem for 5 seasons on a supermodifed. I bring this up because I see them built this way every once in awhile. It may be convenient for packaging, but it doesn't work with big hp and big tires.
