I've kinda been trying to avoid this, but here goes. We don't make a triangulated 4-bar, even though we could. I know that Ford, GM and others did, but they also made Pintos and Vegas. So, here's the thing, in a tri set up, three of the four bars are ALWAYS moving in conflicting arcs, which means the bushings are in a bind, or binding. You can use a piviting bushing, such as a rod end or a pivit ball, or a really soft bushing. But, will it drive and handle as good as a quality 5 link set up? I doubt it.
