The transverse torsion bar front end has a big problem with suspension geometry.

I have a friend who bought a mid '50s ford pickup with one, and it seems to have been installed wrong. The truck was actually dangerous to drive. It required a lot of dedication from a front end shop to get it so it felt safe on the highway.

The Dakota front end is a much better design, technically. Shoot, the '55 front end is probably better. As disk brake kits and rebuild parts are available, why swap at all? Even dropped spindles can be found.
